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.
