In the 1865 Iowa State Senate elections,
Iowa voters elected state senators to serve in the eleventh
Iowa General Assembly. Following the expansion of the
Iowa Senate from 46 to 48 seats in 1865, elections were held for 23 of the state senate's 48 seats.[e] State senators serve four-year terms in the
Iowa State Senate.
To claim control of the chamber from
Republicans, the
Democrats needed to net 20 Senate seats.
Republicans maintained control of the
Iowa State Senate following the election with the balance of power shifting to
Republicans holding 42 seats and
Democrats having six seats (a net gain of 1 seat each for Republicans and Democrats).[a]
