The 1982 Iowa State Senate elections took place as part of the biennial 1982 United States elections. Iowa voters elected state senators in 29 of the state senate's 50 districts—all 25 of the odd-numbered seats were up for regularly-scheduled elections to four-year terms and, due to the oddities of redistricting following the 1980 Census, four of the even-numbered seats were up as well. State senators serve four-year terms in the Iowa State Senate, with half of the seats traditionally up for election each cycle.
