This article contains opinion polling by U.S. state for the 2012 Republican Party presidential primaries.

As of November 2011, only Herman Cain, Newt Gingrich, Rick Perry, and Mitt Romney are able to win polls in multiple states. They are also the only candidates to reach at least 20 percent in polls in multiple states. Before announcing that he would not run, Mike Huckabee was also winning polls in multiple states with numbers above 20%. Michele Bachmann, Sarah Palin and Newt Gingrich were all able to win polls in multiple states earlier in the race, but Bachmann has since seen a drop in support, Palin has announced that she will not run and Gingrich saw a drop in support before a recent turnaround. At some point in the polling, Haley Barbour (MS), Jeb Bush (FL), Chris Christie (NJ), Jim DeMint (SC), Bobby Jindal (LA), Tim Pawlenty (MN), Paul Ryan (WI) and John Thune (SD) all succeeded in leading polls in their home states, although only Pawlenty actually launched a campaign. Pawlenty has since left the race.
