1867 Iowa Senate election

In the 1867 Iowa State Senate elections, Iowa voters elected state senators to serve in the twelfth Iowa General Assembly. Following the expansion of the Iowa Senate from 48 to 49 seats in 1867, elections were held for 34 of the state senate's 49 seats. State senators serve four-year terms in the Iowa State Senate.

The general election took place on October 8, 1867.

Following the previous election in 1865, Republicans had control of the Iowa Senate with 42 seats to Democrats' six 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 election with the balance of power shifting to Republicans holding 40 seats, Democrats having eight seats, and a lone seat for the People's Party (a net gain of 2 seats for Democrats and 1 seat for the People's Party).
