In the 1877 Iowa State Senate elections, Iowa voters elected state senators to serve in the seventeenth Iowa General Assembly. Elections were held in 24 of the state senate's 50 districts. State senators serve four-year terms in the Iowa State Senate.
The general election took place on October 9, 1877.
Following the previous election, Republicans had control of the Iowa Senate with 40 seats to Democrats' 10 seats.
To claim control of the chamber from Republicans, the Democrats needed to net 16 Senate seats.
Republicans maintained control of the Iowa State Senate following the 1877 general election with the balance of power shifting to Republicans holding 38 seats and Democrats having 12 seats (a net gain of 2 seats for Democrats).
