The 1986 United States Senate elections was an election for the United States Senate in the middle of Ronald Reagan's second presidential term. The Republicans had to defend an unusually large number of freshman Senate incumbents who had been elected on President Ronald Reagan's coattails in 1980. Democrats won a net of eight seats, defeating seven freshman incumbents, picking up two Republican-held open seats and regaining control of the Senate for the first time since January 1981. This remains the most recent midterm election in which the sitting president's party suffered net losses while still flipping a Senate seat.
