Elections for all 67 seats in the Minnesota Senate will be held on November 3, 2026.

Democrats hold a 34–33 majority. If Democrats win 45 seats, they would gain a veto-proof majority. If Republicans win 34 seats, they would gain control of the Senate for the first time since 2022.

The 2022 Senate elections replaced the chamber's 34-seat Republican majority with a 34-seat Democratic majority, ending a period of Republican control that began after the 2016 elections. In 2022, Democrats won all five statewide partisan elections in Minnesota. In 2024, Democrats won the statewide elections for president and U.S. Senate as well as four of eight U.S. House elections. Republicans won the other four U.S. House elections. The most recent Minnesota Republican to win a statewide election is Tim Pawlenty (R), who was elected governor in 2006.

Twenty-six of 34 Democrats and 23 of 33 Republicans are running for re-election. Democrats are running in all 67 Senate districts and Republicans are running in 63 Senate districts. Six incumbents – three Democrats and three Republicans – are running for re-election in districts where their party's 2024 presidential nominee placed second.

Ballotpedia identified 17 of the 67 districts as battlegrounds based on past election results. The 17 battleground districts include four districts without an incumbent running and five with competitive fundraising among the candidates. Eleven battleground districts have a Republican incumbent and six have a Democratic incumbent.

The Minnesota Senate elections could change the state's trifecta status. Neither party has a trifecta. Governor Tim Walz is a Democrat and Democrats have a majority in the Senate. Control of the House is split with neither party holding a majority. The governorship and all 134 seats in the House are also up for election. If one party wins the governorship and majorities in both chambers of the Legislature, that party will gain a trifecta.

The Minnesota Senate is one of 88 state legislative chambers with elections in 2026. There are 99 chambers throughout the country.
