The Sixty-Ninth Wisconsin Legislature convened from January 12, 1949, to September 13, 1949, in regular session.

[1] This session saw the first legislative terms of Gaylord Nelson, Patrick Lucey, Ruth Bachhuber Doyle, and Robert T. Huber, all of whom would—over the course of the subsequent two decades—play important roles in the transition of the Democratic Party of Wisconsin from a permanent minority party to competitive status with the state Republican Party, by winning over many former Wisconsin Progressive Party voters.

Senators representing even-numbered districts were newly elected for this session and were serving the first two years of a four-year term.

[1] The governor of Wisconsin during this entire term was Republican Oscar Rennebohm, of Dane County, serving his first full two-year term, having won election in the 1948 Wisconsin gubernatorial election.

He had previously been elected lieutenant governor in 1946, and ascended to the gubernatorial office following the death of governor Walter Samuel Goodland in March 1947.
