Brigden is a community in the township of St. Clair, Lambton County, Ontario, Canada.

The community is located at the crossroads of Courtright Line and Brigden Road, between Kimball to the west and Oil City to the east, and about 20 kilometres (12 mi) southeast of the city of Sarnia.

Brigden has a population of about 500 and is the centre of a thriving agricultural district.

The community is situated on the former Michigan Central Railroad line and thus is named after William Wharton Brigden, one of the engineers who surveyed the railway in 1936.

Brigden died of a heart attack on May 26, 1939, in Battle Creek, Michigan, where he was the superintendent of the city waterworks.
