All 203 seats in the Pennsylvania House of Representatives are up for election on November 3, 2026.

Currently, Democrats have a 103-100 majority in the House. This means Republicans need to gain at least two seats to win a majority and Democrats can lose no more than one seat to retain their majority.

Pennsylvania is one of 11 states with a divided government ahead of the general elections. Democrats control the governorship and the state House, while Republicans control the state Senate. The state has had a divided government since 2015. The last time the state had a Democratic trifecta was in 1993, and the last time it had a Republican trifecta was in 2014. Ballotpedia assessed a moderate possibility of either party gaining a trifecta as a result of the 2026 general elections.

According to Spotlight PA’s Stephen Caruso, since Democrats won control of the House in 2022, lawmakers "have struggled to advance far-reaching legislation on energy, transportation, or health care. Even passing a statutorily required budget to fund schools, counties, and nonprofits proved to be a challenge.” Caruso listed the Lehigh Valley, Northeast Pennsylvania, and western coal country as the most competitive parts of the state for the House.

Both the Democratic Legislative Campaign Committee (DLCC) and the Republican State Leadership Committee (RSLC) are targeting the Pennsylvania General Assembly in the 2026 general elections. According to a Ballotpedia analysis, Pennsylvania is one of 30 states where both parties are targeting districts in a state legislature.

The Democratic Legislative Campaign Committee (DLCC) is targeting 18 House seats, including 10 the Democrats already hold. The Republican State Leadership Committee (RSLC) is targeting nine House seats, including seven the Republicans already hold.

Ballotpedia considers 24 districts to be battlegrounds. These include districts that had a margin of victory within five percentage points in 2024, DLCC and RSLC targets, and districts with an election forecast rating of Toss-up, Lean D/R, or Tilt D/R.

Democrats represent 11 battlegrounds and Republicans represent 13. Three battleground districts are open, while the other 21 have an incumbent running. To read more about these districts, click here.
