Foyle was a single member constituency in the Parliament of Northern Ireland. It was created in 1929 as one of the five single-member constituencies replacing the former five-member Londonderry constituency. The constituency continued in existence until the Parliament was temporarily suspended in 1972, and then formally abolished in 1973.

The seat was held continuously by nationalist candidates and never even contested by unionists, although labour movement candidates sometimes polled well.
