Austin Knudsen (R) defeated Raph Graybill (D) in the election for Montana attorney general. Incumbent Tim Fox (R) did not run for re-election. Montana’s attorney general is the state’s chief legal officer, chief law enforcement officer, and director of the Montana Department of Justice.

The results of Montana’s gubernatorial, attorney general, and secretary of state elections transitioned the state from divided triplex control to Republican triplex control. Before the election, both the secretary of state and attorney general were Republicans and the governor was a Democrat. Greg Gianforte (R) won the gubernatorial race, and Republicans won both other offices.
