Colfax is the largest town and parish seat of Grant Parish, Louisiana, United States. The town, founded in 1869, is named for the vice president of the United States, Schuyler M. Colfax, who served in the first term of U.S. President Ulysses S. Grant, for whom the parish is named. Colfax is part of the Alexandria, Louisiana Metropolitan Statistical Area. The population was 1,659 at the 2000 census.
The first weekend of November Colfax hosts the annual Louisiana Pecan Festival, an outgrowth of the centennial celebration of the town held in 1969. The festival, which draws large crowds to Colfax, includes a parade, fireworks, carnival rides, music, and the unveiling of Miss Louisiana Pecan Festival and her court. Pecans are sold whole, cracked, or shelled in bags of ten, fifteen, or twenty pounds and may also be purchased in pie or brittle form.
