The 1986 Connecticut State Senate elections took place as a part of the biennial 1986 United States elections. All 36 seats were up for re-election. Senators serve two-year terms and are up for re-election every election cycle.

The Democrats, led by minority leader Cornelius O'Leary, flipped control of the State Senate. They managed to gain a two-thirds majority over the Republicans, achieving a supermajority. This was in large part attributed to the popularity of incumbent Democratic governor William O'Neill and his landslide re-election, having a coattail effect boosting down-ballot Connecticut Democrats due to the state's improved economy, with it also leading to them reclaiming the state house.

Retirements Two incumbents did not seek re-election.

Republicans District 5: Anne Streeter retired. District 26: John Grennell Matthews retired.

Special elections One special election was called for the 25th district due to Republican Senator Andrew Santaniello's unexpected death on March 15, 1986. The date of the election was held on May 6, 1986. Republican councilman Joseph Santo managed to beat former Democratic state representative John Atkin, and held the seat Republican.

However, in the general election on November 4, Atkin managed to unseat Santo in a rematch, flipping the seat Democratic.

Incumbents defeated Twelve incumbents, all Republicans, were defeated in general elections.
