Who serves in the South Dakota Senate?

Current members. Traceable sources.

This is a dated current-member snapshot. Membership follows the active term identified by the official chamber directory. A candidate list or vote lead does not establish a serving member. This view does not refresh automatically.

The official 2026 session 71 directory was checked November 6, 2026. All 105 active identities, district keys and affiliations independently match their individual official session profiles, the official CSV and the printable roster. The current-session API explicitly identifies session 71 as current; the already visible 2027 session is not substituted for the serving term.

The House has 70 serving members: 65 Republican and five Democratic. The Senate has 35 serving members: 32 Republican and three Democratic. All seats are filled in the checked official source; disappearing candidate names or November election outcomes do not establish vacancies.

House geography has 37 polygons for 70 member seats. Districts 26 and 28 each have two single-member House subdistricts: 26A/26B and 28A/28B. The other 33 House districts each have two members sharing one polygon. The Senate has 35 numbered districts, each with one senator. District 4 is not split in this state plan.

The January 2026 journals certify current appointments including Nick Fosness, Tim Czmowski, Jack Kolbeck and John Shubeck in the House, and Brandon Wipf in the Senate. Current profiles retain these replacements. Directory status codes New Member, Incumbent, Appointed and Other House describe experience or appointment; they are not vacancies or party codes.

House Districts 10 and 32 have members with different affiliations and use one stripe per member seat. Peri Pourier’s official serving affiliation is Republican. A candidate’s different ballot label in a later contest is not substituted for the published current serving affiliation.

Constitution Article III section 6 establishes two-year legislative terms. SDCL 3-1 separately addresses January qualification, commencement and oath requirements, subject to express exceptions; Article III section 7 separately sets the annual session for the second Tuesday of January. The next regular session opens January 12, 2027. No November winner is promoted into this November 6 serving snapshot.

The official current map continues to publish the adopted 2021 legislative plan. HB 1001’s enrolled provisions and current codified district law support its 35 Senate districts, shared House districts and four single-member House subdistricts. State legislative boundaries are kept separate from the single at-large U.S. House seat.

These maps describe state legislative representation. No district demographic estimate, ZIP finding or ZCTA claim is inferred from the statewide 2024 ACS authority. This dated snapshot does not refresh automatically.

Affiliations follow the checked individual official 2026 profiles and independent official roster views. Shared House districts show every member; mixed affiliations have one stripe per seat. Party totals count member seats, not district area, population or vote share.

Small-scale Census 2024 1:500,000 state legislative display polygons, checked against the Legislature’s current adopted 2021 legal map polygons by exact district ID, label and outer-component interior. All source display rings are retained. There are 37 House geographic districts for 70 member seats and 35 Senate districts. This is not address-level district determination.
