Swinford, ("ford-mouth of the pig"), is a town in County Mayo, Ireland. It is surrounded by the settlements of Midfield, Meelick, Culmore, Cloonaghboy, Killasser, Kinaffe and other villages. It is just off the N5 road, located 18 km (11 mi) from Ireland West Airport Knock (formerly known as Knock International Airport). Situated on a tributary of the River Moy, Swinford is known for its fishing waters, including the Callow lakes and the lakes of Conn and Cullin. Swinford was bypassed in 1993 by the N5 route and was the first town in Mayo to be bypassed.

Swinford hosts one of County Mayo's largest summer festivals and has done since the mid-1980s: Siamsa Sraide Swinford, (Fun in the Streets of Swinford). This street festival of pageantry, céilí dancing, and heritage displays depicts the traditions of East Mayo. The five-day festival takes place in the first week of August and features live bands playing open-air concerts as well as a heritage day, history walks and an busking competition.-

Swinford is used for the filming of TV show Hardy Bucks, as the fictional town of Castletown.
