103rd Wisconsin Legislature

The One Hundred Third Wisconsin Legislature convened from January 3, 2017, to January 7, 2019, in regular session, though it adjourned for legislative activity on May 9, 2018. The Legislature also held four extraordinary sessions and four special sessions during the legislative term.

The most notable work of this legislature occurred in the last month of the term, at the extraordinary sessions after the 2018 election, in which the Republican Legislature and outgoing Republican governor passed laws to limit powers of the incoming Democratic governor and attorney general.

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 held on November 8, 2016. Senators representing odd-numbered districts were serving the third and fourth year of their four-year term, having been elected in the general election held on November 4, 2014.
