Michael Gronstal Democratic Leonard Boswell Democratic The 1992 Iowa State Senate elections took place as part of the biennial 1992 United States elections.

Iowa voters elected state senators in 32 of the state senate's 50 districts—all 25 of the even-numbered seats were up for regularly-scheduled elections and, due to the oddities of redistricting following the 1990 Census, seven of the odd-numbered seats were up as well.

On December 17, 1991, a special election in district 44 resulted in Albert Sorensen flipping a seat in favor of the Democrats.

Therefore, on election day in November 1992, Democrats controlled 29 seats and Republicans had 21.

To reclaim control of the chamber from Democrats, the Republicans needed to net 5 Senate seats.
