63rd Wisconsin Legislature

The Sixty-Third Wisconsin Legislature convened from January 13, 1937, to July 2, 1937, in regular session, and reconvened in a special session from September 15, 1937, to October 16, 1937.

This was the high water mark for the power of the Wisconsin Progressive Party, as they controlled both chambers of the Legislature and the Governor's office.

Senators representing even-numbered districts were newly elected for this session and were serving the first two years of a four-year term. Assembly members were elected to a two-year term. Assembly members and even-numbered senators were elected in the general election of November 3, 1936. Senators representing odd-numbered districts were serving the third and fourth year of a four-year term, having been elected in the general election of November 6, 1934.

The governor of Wisconsin during this entire term was Progressive Philip La Follette, of Dane County, serving his third two-year term, having won re-election in the 1936 Wisconsin gubernatorial election.
