Brunlanes is a parish and former municipality within Larvik municipality in Vestfold county, Norway. It was annexed by Larvik on January 1, 1988. The administrative centre of the municipality was located in the adjacent villages of Nevlunghavn and Helgeroa. Arguably the best soil in Vestfold County can be found in Brunlanes, and farming is the main industry with considerable vegetable- and corn cultivation. It is home to Berg Old Church at Berg, which was erected in the 1100s, but laid in ruins by the 1960s. The church had been rebuilt and features a clear-cut architecture with a red tilestone roof.
