The 2012 Connecticut Republican presidential primary took place on April 24, 2012. It was a closed primary, open only to Republican electors. 25 of the state's 28 delegates to the 2012 Republican National Convention were decided by the primary outcome, with the other 3 being superdelegates: the state party chairman and the state's two Republican National Committee representatives.

Mitt Romney won the primary by a wide margin, garnering two-thirds of the vote. Only 14.4% of active registered Republicans participated in the primary, the lowest turnout since the primary format was put in place in the state in 1980.

Process After switching from proportional distribution of delegates to a winner-take-all system in 1996, the Connecticut Republican Party voted in September 2011 to award delegates by a hybrid winner-take-all and proportional distribution process beginning with the 2012 primary. Of the 25 regular delegates at stake in the primary, the party called for three delegates to be awarded to the winner of each of the state's five congressional districts on a winner-take-all basis for a total of 15 delegates. The remaining 10 would be distributed proportionally based on the statewide vote total among candidates receiving at least 20% support unless a candidate won a majority of the statewide vote, in which case the candidate would receive all 10 of these delegates.
