Beauséjour riding (formerly known as Beauséjour—Petitcodiac) is a federal electoral district in eastern New Brunswick, Canada, which has been represented in the House of Commons of Canada since 1988. It replaced Westmorland—Kent, which was represented from 1968 to 1988.

Beauséjour is largely Acadian and Francophone, with a significant Anglophone section in the southern section of the riding.

The riding consists of most of Westmorland County to the east and north of Moncton; and almost all of Kent County. Major towns in the riding include Shediac, Cap-Pelé, Sackville, Bouctouche and Richibucto. The neighbouring ridings are Miramichi—Grand Lake, Fundy Royal, Moncton—Riverview—Dieppe, and Cumberland—Colchester in Nova Scotia; it is connected to the riding of Malpeque on Prince Edward Island by the Confederation Bridge.

Westmorland—Kent was created in 1966 from Kent, and part of Westmorland that was not included in the Moncton riding. It was abolished when it was incorporated into the new riding of Beauséjour in 1987.
