The 1926 Iowa State Senate elections took place as part of the biennial 1926 United States elections.

A statewide map of the 50 state Senate districts in the 1926 elections is provided by the Iowa General Assembly here.

Republicans maintained control of the Iowa State Senate following the 1926 general election with the balance of power shifting to Republicans holding 49 seats and Democrats having 1 seat (a net gain of 4 seats for Republicans).

Like 6 years prior, Democrats lost every district up for election, including four held by them.

After the election, Lloyd Ellis of the 3rd Senate District was the only Democrat in the chamber.
