This is a timeline of women's suffrage in Pennsylvania. Activists in the state began working towards women's rights in the early 1850s, when two women's rights conventions discussed women's suffrage. A statewide group, the Pennsylvania Woman Suffrage Association (PWSA), was formed in 1869. Other regional groups were formed throughout the state over the years. Suffragists in Pittsburgh created the "Pittsburgh Plan" in 1911. In 1915, a campaign to influence voters to support women's suffrage on the November 2 referendum took place. Despite these efforts, the referendum failed. On June 24, 1919, Pennsylvania became the seventh state to ratify the Nineteenth Amendment. Pennsylvania women voted for the first time on November 2, 1920.
