Misamis Occidental's at-large congressional district

Misamis Occidental's at-large congressional district is an obsolete congressional district of the Philippines that encompassed the entire province of Misamis Occidental. It was created ahead of the 1931 Philippine House of Representatives elections following the 1929 division of Misamis into two provinces. The district elected one member to the final two meetings of the Philippine Assembly from 1931 to 1935 and to the Commonwealth National Assembly from 1935 to 1941.

Two members represented the district in the Second Republic National Assembly from 1943 to 1944. It returned to a single-member constituency for the restored House of Representatives in both the Commonwealth Congress from 1945 to 1946 and all seven meetings post-independence until 1972. The district was last contested at the 1984 Philippine parliamentary election and was abolished following the 1987 reapportionment under a new constitution.
