Hugh L. White Democratic James P. Coleman Democratic The 1955 Mississippi gubernatorial election took place on November 8, 1955, in order to elect the Governor of Mississippi.

Incumbent Democrat Hugh L. White was term-limited, and could not run for reelection to a second term.

As was common at the time, the Democratic candidate ran unopposed in the general election, so therefore the Democratic primary was the real contest, and winning the primary was considered tantamount to election.

The runoff election was won by Attorney General James P. Coleman, who defeated lawyer Paul B. Johnson Jr., son of former Governor Paul B. Johnson Sr.

In the general election, Coleman ran unopposed.
