Brooklin is a town in Hancock County, Maine, United States. The population was 824 at the 2010 census. It is home to WoodenBoat Magazine, Brooklin Boat Yard, and numerous boatbuilders, artists, writers, musicians, and potters.

Brooklin was originally part of a larger town, then Sedgwick broke off and formed its own town. A few weeks later, the name was changed to Brooklin, after the brook line which separated it from Sedgwick. Using porgy oil as a fertilizer, the difficult soil was made productive, and hay became the principal crop. With excellent harbors, however, the main occupations were fishing and seafaring. By 1859, when the population was 1,002, it also had five boot and shoemaking factories, as well as two barrel manufacturers. By 1886, the town was noted for producing smoked herring in considerable quantities. Canning lobster had also become an important business.
