Mary Kramer Republican Mary Kramer Republican The 2002 Iowa State Senate elections took place as part of the biennial 2002 United States elections.

Iowa voters elected state senators in 35 of the state senate's 50 districts—all 25 of the odd-numbered seats were up for regularly-scheduled elections and, due to the oddities of redistricting following the 2000 Census, 10 of the even-numbered sears were up as well.

On March 12, 2002, a special election in district 10 resulted in Amanda Ragan flipping a seat in favor of the Democrats.

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

Republicans maintained control of the Iowa State Senate following the 2002 general election with the balance of power remaining unchanged with Republicans holding 29 seats and Democrats having 21 seats.
