Americans and others who are not native Europeans from Portugal but originate from countries that were former colonies of Portugal do not necessarily self-identify as "Portuguese American", but rather as their post-colonial nationalities, although many refugees (referred to as retornados) from former Portuguese colonies, as well as many white Brazilians, are ethnically or ancestrally Portuguese. In 2017, an estimated 48,158 Portuguese nationals were living in the United States.^[2]

Some Melungeon communities in rural Appalachia have historically self-identified as Portuguese. Given their complex ancestry, individual Melungeons may descend from Portuguese people, but not all do.

Bilateral ties date from the earliest years of the United States. Following the American Revolutionary War, Portugal was the first neutral country to recognize the United States.^[3]

Portuguese people have had a very long history in the United States, since 1634. The first documented Portuguese to live in colonial America was Mathias de Sousa, possibly a Sephardic Jew of mixed African background.^[4] The oldest synagogue in the country, the Touro Synagogue, is named after one of these early Portuguese Jews, Isaac Touro.

.

Some of the earliest European explorers to reach continental North America in the Age of Discovery were Portuguese explorers, such as João Fernandes Lavrador. Navigators, like the Miguel Corte-Real family, may have visited the North American shores at the beginning of the 16th century.^[5] João Rodrigues Cabrilho was a Portuguese navigator who became the first European to reach California in 1542.

There is a historic landmark, the Dighton Rock, in Southeastern Massachusetts, that a small minority of scholars believe testifies their presence in the area. Portuguese explorer João Rodrigues Cabrilho explored the California coast for the first time.

During the Colonial period, there was a small Portuguese immigration to the present-day U.S., especially to the islands of Martha's Vineyard and Nantucket.

Peter Francisco, the giant soldier in the Continental Army, is generally thought to have been born Portuguese, from the Azores.

In the late 19th century, many Portuguese, mainly Azoreans and Madeirans, emigrated to the eastern U.S., establishing communities in New England coastal cities, primarily but not limited to Tiverton, East Providence, Valley Falls, and Pawtucket in Rhode Island,^[6] and Taunton, Brockton, Fall River, and New Bedford in Southeastern Massachusetts.

In the 1840s, whaling ships were the way to get to America, after a slow voyage of two to three years.^[7] In the early 1700s, Massachusetts dominated the whaling industry with Nantucket, Cape Cod and New Bedford. By the early 19th century, New Bedford had become the center of whaling in America. When whalers were out at sea, they would frequently stop in the Azores to recruit crew members for help.^[7] At the end of their voyage, they docked in New England, where crew members often settled as immigrants. Today, one can visit the Whaling Museum in New Bedford, Massachusetts and encounter authentic Portuguese whaling history.^[7]

Another part of Massachusetts that attracted many Portuguese immigrants was Northern Massachusetts, most notably Lowell and Lawrence. In addition, Many Portuguese immigrants also went to nearby Southern New Hampshire. Massachusetts was a key location for Portuguese immigrants due to the availability of low skill jobs. Many migrants came to the United States with little knowledge of the English Language, and textile jobs were frequently available in these areas. Portuguese migrants had to seek out low skill jobs because of education in Portugal and the lack of job availability in the nineteenth century.

A number of Portuguese immigrants settled in the city of Boston. These Portuguese immigrants mainly settled in East Boston and North End. In addition, many Portuguese immigrants also went to Cambridge and Somerville.

A Portuguese community existed in the vicinity of the Carpenter Street Underpass in Springfield, Illinois, one of the earliest and largest Portuguese settlements in the Midwestern United States. By the early twentieth century, the project area represented the western extension of a neighborhood known as the "Badlands." The Badlands was included in the widespread destruction and violence of the Springfield Race Riot in August 1908, an event that led to the formation of the National Association for the Advancement of Colored People (NAACP). The Carpenter Street archaeological site possesses local and national significance for its potential to contribute to an understanding of the lifestyles of multiple ethnic/racial groups in Springfield during the nineteenth and early twentieth centuries.^[8]

On the West Coast in California there are Portuguese communities in San Francisco, Oakland, San Jose, Santa Cruz, as well as in dairy farming areas in the Central Valley, the Los Angeles Basin, and San Diego, in connection to Portuguese fishermen and settlers emigrating to California from the Azores. There are also connections with Portuguese communities in the Pacific Northwest in Astoria, Oregon, and Seattle, Washington, and British Columbia, Canada as well.

Many of the Portuguese communities on the west coast were farming towns. Portuguese who moved to California often saved money to buy land to start farming. Portuguese farmers in California and along the west coast of the United States often hired other Portuguese migrants as farm hands. Aside from farming Portuguese migrants also were able to secure jobs as fishermen in port cities.^[9]

Portuguese migration to Hawaii occurred often in the late nineteenth century due to the availability of labor contracts on the islands. Labor contracts paid for the migration of entire families. This was enticing for families looking to migrate without the means or the desire to migrate in stages. This led to families having to work off debt before they could move off of the island. Often times Portuguese migrants decided just to remain in Hawaii despite there being little opportunity for improving their lives.^[9]

Portuguese Community In San Diego

The San Diego Portuguese Community is filled with a rich history, affecting San Diego as we know it. In 1876, the earliest Portuguese community members immigrated to Point Loma San Diego, California. A blend of Portuguese immigrants moved from the mainland of Portugal, along with the Azorean and Madeira Islands, moving toward the United States. The community landed on the West Coast along with several areas on the East, producing new and diverse mixes of traditions and faiths. In 1908, the Portuguese began fishing for tuna, which before this, was never considered a fish to be commercially marketed. By 1911, the first tuna canneries had opened and the community continued to grow. By the 1920s, the Portuguese and Italians dominated the fishing industry.^[2] The fishing industry has a huge importance within the history of the Portuguese community and the history of San Diego because it is the way that the Portuguese had their start in America, along with shaping the way we see the food industry in San Diego. The growth in the food industry has had a big impact on San Diego’s history because it helped bring in money and progress the city into what it is today. The fishing industry was a huge part of the growing Portuguese community, and as the fishing industry developed, the center of the Portuguese community moved two miles east of La Playa to the Roseville area. Throughout this time, it was clear that the fishing industry was not only a business, but a lifestyle that included the whole family. ^[3]

20th century

After World War II, there was another wave of Portuguese immigration to the country, mainly in the northeastern United States (New Jersey, New York, Connecticut, Rhode Island, Massachusetts and Maryland), and also in California. Many were fleeing the right-wing dictatorship of Antonio Salazar. There are Portuguese clubs, principally in the larger cities of these states, which operate with the intention of promoting sociocultural preservation as venues for community events, athletics, etc.

Many Portuguese Americans may include descendants of Portuguese settlers born in Africa (like Angola, Cape Verde, and Mozambique) and Asia (mostly Macanese people), as well Oceania (Timor-Leste). There were around one million Portuguese Americans in the United States by 2000.

A general contribution the Portuguese people have made to American music is the ukulele, which originated in Madeira and was initially popularized in the Kingdom of Hawaii.^[10] John Philip Sousa was a famous Portuguese American composer most known for his patriotic compositions.

A large amount of mingling took place between Chinese and Portuguese in Hawaii.^[11] There were very few marriages between European and Chinese people with the majority being between Portuguese and Chinese people.^[12]^[13] These unions between Chinese men and Portuguese women resulted in children of mixed parentage, called Chinese-Portuguese. For two years to June 30, 1933, 38 of these children were born; they were classified as pure Chinese because their fathers were Chinese.^[14] Curiously, these marriages are in marked contrast to the situation in Macau, where very few Han Chinese married Portuguese settlers; instead, the Portuguese mixed with indigenous Tanka people, leading to the Macanese people.^[15]

As with other immigrants that arrived in America, several Portuguese surnames have been changed to align with more American sounding names, for example Rodrigues to Rogers, Oliveira to Oliver, Martins to Martin, Pereira to Perry, Moraes or Morais to Morris, Magalhães to McLean, Souto to Sutton, Moura to Moore, Serrão to Serran, Silva to Silver or Sylvia, Rocha to Rock (or Stone), Madeira or Madeiros to Wood, Pontes to Bridges, Fernandes to Frederick, Costa to Charlie, Emo or Emos to Emma and Santos to Stan.

Azorean Refugee Act of 1958

In 1957–58, the Capelinhos volcano erupted on the Azorean island of Faial, causing massive destruction from lava and smoke. In response, then Senators John F. Kennedy and John Pastore co-sponsored an Azorean Refugee Act.^[16]

President Dwight Eisenhower signed the legislation in 1958, making 1,500 visas available to the victims of the eruption.^[17] An extension was enabled in 1962, providing opportunities for even more immigrants. According to the United States Census from 2000, there were 1,176,615 Portuguese-Americans, the majority being of Azorean descent.

This led to the passing of the 1965 Immigration Act, which stated if someone has legal or American relatives in the United States, they could serve as a sponsor and, therefore could be a legal alien. This act dramatically increased Portuguese immigration into the 1970s and 1980s.^[7]

There are four anthologies of Portuguese-American literature: Luso-American Literature: Writings by Portuguese-Speaking Authors in North America edited by Robert Henry Moser and António Luciano de Andrade Tosta and published in 2011, The Gávea-Brown Book of Portuguese-American Poetry edited by Alice R. Clemente and George Monteiro, published in 2013, Writers of the Portuguese Diaspora in the United States and Canada: An Anthology edited by Luís Gonçalves and Carlo Matos, published in 2015, and Behind the Stars, More Stars: The Tagus/Disquiet Collection of New Luso-American Writing edited by Christopher Larkosh and Oona Patrick, published in 2019 by Tagus Press.

A list of accomplished writers include: Katherine Vaz, Frank X. Gaspar, Millicent Borges Accardi, Sam Pereira, Nancy Vieira Couto, Alfred Lewis, Charles Reis Felix, Michael Garcia Spring and John dos Passos.

In recent years, the Portuguese in the Americas Series at Tagus Press at UMass Dartmouth has been particularly active in publishing works by Portuguese-American authors, the most recent of these being The Poems of Renata Ferreira, by Frank X. Gaspar, published in 2020.

Portuguese-Americans are the fourth largest ethnic group in the state of Hawaii, fifth largest group in Rhode Island and the eighth largest group in Massachusetts.^[18]
