Carp is a large village west of urban Ottawa, Ontario, Canada.

The village takes its name from the Carp River which runs through the village. The main street was formerly a section of the Trans-Canada Highway and carried much of the traffic coming from the west into Ottawa. However the village has been bypassed with the development of the Highway 417.

Carp was a rail stop on the Carleton Place, Arnprior, Renfrew Pembroke line, CARP.

With the amalgamation of municipal governments in the region in 2001, Carp is now governed as part of the new city of Ottawa. Carp is used as a mailing address for large areas of the former West Carleton Township. As such, residents of this large area will identify themselves as living in Carp although they may live large distances from the village proper.

Carp's main attraction is the Diefenbunker, a Cold War museum located just north of the village, and was featured in the film The Sum of All Fears. Other attractions include a large farmers' market which is held each Saturday from May to October. The Carp Fair, held each year since 1880, is in September and is now located at the fairgrounds. The fair attracts people from all over the city every year.
