Scott Kevin Walker is an American politician who served as the 45th governor of Wisconsin from 2011 to 2019. A member of the Republican Party, he previously served as Milwaukee County executive from 2002 to 2010.

The governor of Wisconsin is the head of government of Wisconsin and the commander-in-chief of the state's army and air forces. The governor has a duty to enforce state laws, and the power to either approve or veto bills passed by the Wisconsin Legislature, to convene the legislature, and to grant pardons, except in cases of treason and impeachment. The position was first filled by Nelson Dewey on June 7, 1848, the year Wisconsin became a state. Prior to statehood, there were four governors of Wisconsin Territory.
