The primary election on June 6, 1938, determined which candidates appeared on the November 8, 1938 general election ballot.
Following the previous election, Republicans had control of the Iowa state Senate with 28 seats to Democrats' 22 seats. Following a special election in 1937 in district 1, Republicans flipped the first district to their party. Therefore, on election day in November 1938, Republicans held 29 seats to Democrats' 21.
To claim control of the chamber from Republicans, the Democrats needed to net 5 Senate seats.
Republicans maintained control of the Iowa State Senate following the 1938 general election with the balance of power shifting to Republicans holding 38 seats and Democrats having 12 seats.
