The 1924 Iowa Senate elections took place as part of the biennial 1924 United States elections. Iowa voters elected state senators in 29 of the senate's 50 districts. State senators serve four-year terms in the Iowa Senate. A statewide map of the 50 state Senate districts in the 1924 elections is provided by the Iowa General Assembly here. The primary election on June 2, 1924, determined which candidates appeared on the November 4, 1924 general election ballot. To claim control of the chamber from Republicans, the Democrats needed to net 22 Senate seats.
