New York's 25th congressional district is acongressional district for theUnited States House of Representatives. It is currently represented by DemocratJoseph Morelle. Since 2023, the district has been located withinMonroe County and part ofOntario County, centered on the city ofRochester.

Former representativeLouise Slaughter, who had represented Rochester in Congress since 1987, died while in office in March 2018, leaving the seat vacant until that year’s general election.

Historically, most of this district was located inUpstate New York. In the 1960s, the 25th district was aWestchester/Rockland seat, covering areas now in the17th and18th districts. In the 1970s it was the lowerHudson Valley district and congruent to the present19th district. Onondaga County was split between the32nd district (which included rural counties east of Syracuse now in the23rd and24th districts) and the33rd district (which included the Finger Lakes counties in the 24th and29th districts).

In the 1980s, the district was centered in theUtica area (now the 24th district), and theSyracuse area was entirely in the27th district. From 2003 to 2013, it stretched fromSyracuse to the northeastern suburbs of Rochester. The district comprisedOnondaga andWayne counties, the northernmost portion ofCayuga County, and the towns ofIrondequoit,Penfield, andWebster inMonroe County. The district included 100 miles ofLake Ontario shoreline, the easternmostFinger Lakes, and significant portions of theErie Canal.

For the119th and successive Congresses (based on the districts drawn following the New York Court of Appeals' December 2023 decision inHoffman v New York State Ind. Redistricting. Commn.), the district contains all or portions of the following counties, towns, and municipalities.^[8][9]
