Who is my Wisconsin legislator?

The Wisconsin Legislature has 33 Senate districts and 99 Assembly districts. Both are drawn over the same ground and neither follows a city, county or ZIP boundary, so the only way to know which pair covers an address is to put the address on the map. Senators serve four-year terms and Assembly members two.

What the lookup shows

Two chambers, two maps

An address has one district in each chamber and the two rarely share a boundary: the chambers are apportioned separately, and in several of these states one chamber's districts are built by pairing the other's. The table below lists both in full, so a reader who knows their district number can look up the member without opening the map at all.

Where the names come from

Both rosters are re-read on a schedule from the legislature's own published member lists and land as a reviewed pull request; the map names no officeholder it cannot cite. A seat the source does not name is shown as unnamed rather than filled in.

Who represents each Wisconsin State Senate district

All 33 seats on the Wisconsin State Senate, as this site had them on September 11, 2026. The map above reads the same roster, so a card and this table cannot disagree — but a table is a claim about a day, and this one names its day. Where the roster names nobody it says so rather than guessing. Where these names come from.

Who represents each Wisconsin State Assembly district

All 99 seats on the Wisconsin State Assembly, as this site had them on September 11, 2026. The map above reads the same roster, so a card and this table cannot disagree — but a table is a claim about a day, and this one names its day.
