In the 1871 Iowa State Senate elections, Iowa voters elected state senators to serve in the fourteenth Iowa General Assembly. Elections were held in 34 of the state senate's 49 districts. State senators serve four-year terms in the Iowa State Senate.
The general election took place on October 10, 1871.
Following the previous election, Republicans had control of the Iowa Senate with 43 seats to Democrats' seven seats.
To claim control of the chamber from Republicans, the Democrats needed to net 19 Senate seats.
Republicans maintained control of the Iowa State Senate following the 1871 general election with the balance of power shifting to Republicans holding 42 seats and Democrats having eight seats (a net gain of 1 seat for Democrats).
