1958 United States House of Representatives elections in Mississippi

The 1958 United States House of Representatives elections in Mississippi were held on November 4, 1958, to elect the six U.S. representatives from the state of Mississippi, one from each of the state's six congressional districts. The elections coincided with the United States Senate election. Primary elections were held August 26.

All six Democratic nominees were elected unopposed in the general election, with two facing primary elections.

General election
In 4 of the 6 congressional districts, only one candidate filed to run for the Democratic primary, so primaries were not held in those districts. As no independent or Republican candidate filed to run in the entire state, every Democratic nominee for the general election was elected unopposed.
