The 2020 Iowa State Senate elections took place as part of the biennial 2020 United States state legislative elections. Iowa voters elected state senators in half of the state senate's districts – the 25 even-numbered state senate districts. State senators serve four-year terms in the Iowa Senate, with half of the seats up for election each cycle.
A statewide map of the 50 state Senate districts in the 2020 elections is provided by the Iowa General Assembly here.
The primary election on June 2, 2020, determined which candidates appeared on the November 3 general election ballot. The filing deadline was March 13.[1] [2]
