The 2022 Ohio gubernatorial election was held on November 8, 2022, to elect the governor of Ohio. Incumbent Republican Governor Mike DeWine won a second term in a landslide, defeating Democratic nominee Nan Whaley, the former mayor of Dayton, with 62.4% of the vote. DeWine's 25-point victory marked the continuation of a trend in which every incumbent Republican governor of Ohio since 1994 has won re-election by a double-digit margin.
This was the first time since 1994 in which Trumbull and Mahoning counties have gone to the Republican candidate with over 60% of the vote. Hamilton County also voted Republican in a statewide election for the first time since Ohio's 2016 United States Senate election, which incumbent Republican Rob Portman also won by over 20 points and nearly 60% of the vote.
