The 2020 Wisconsin Senate elections were held on Tuesday, November 3, 2020, at the Fall general election in Wisconsin. 16 of the 33 seats in the Wisconsin Senate were up for election—the even-numbered districts. Before the election, Republicans held 18 seats, Democrats held 13, and two were vacant. Of the seats up for election, seven were held by Republicans, seven were held by Democrats, one was vacated by a Democratic resignation, and one was vacated by a Republican resignation. The primary election was held on August 11, 2020.

Republicans maintained control of the Senate but fell one seat short of a supermajority, defeating one Democratic incumbent and winning an open seat previously held by a Democrat. After the elections, Republicans were set to enter the 105th Wisconsin Legislature with 21 of 33 seats, but one member resigned due to election to another office, leaving them with 20 seats at the start of the legislative term.
