The Fortieth Wisconsin Legislature convened from to in regular session. They met again for two special sessions in June 1892 and October 1892 to pass redistricting laws. The extra sessions were necessitated by court cases which threw out the Legislature's previous attempts at redistricting.

Senators representing even-numbered districts were serving the third and fourth year of a four-year term, having been elected in the general election of November 6, 1888.

The governor of Wisconsin during this entire term was Democrat George Wilbur Peck, of Milwaukee County, serving a two-year term, having won election in the 1890 Wisconsin gubernatorial election.
