Belfast Falls was a constituency of the Parliament of Northern Ireland.

It was created in 1929, when the House of Commons (Method of Voting and Redistribution of Seats) Act (Northern Ireland) 1929 introduced first-past-the-post elections throughout Northern Ireland.

It survived unchanged, returning one member of Parliament, until the Parliament of Northern Ireland was temporarily suspended in 1972, and then formally abolished in 1973.

[1] The constituency was the most staunchly nationalist in Belfast.

It was initially held by Nationalist Party members, then later by a variety of labour movement activists and members of smaller nationalist parties.
