New York’s 27th congressional district was acongressional district for theUnited States House of Representatives in westernNew York. It included all ofOrleans,Genesee,Wyoming, andLivingston counties and parts ofErie,Monroe,Niagara, andOntario counties. The district contained most of the eastern and southern suburbs ofBuffalo, most of the southern suburbs ofRochester, as well as large rural areas to the east and south. The seat was last occupied byRepublicanChris Jacobs, who won aspecial election on June 23, 2020.^[1][2] Previously, it had been vacant from October 1, 2019, when Republican incumbentChris Collins resigned after pleading guilty to charges ofinsider trading.^[3]

The precursor to the district was the central Erie county seat numbered the 30th district in the 1990s. In the 1980s this area was in the 33rd district. In the 1970s it was numbered the 37th district, although certain suburban areas were in the 38th district (later the 31st). None of these districts included theJamestown area, which had always been in the southern tier district (now the 29th district) in prior maps. The 27th district covered the area now in the 26th district in the 1990s and the Syracuse area (now the 25th district) in the 1980s. It was theSouthern Tier seat now numbered the 22nd in the 1970s. In the 1960s this district was in the lowerHudson Valley covering the area now in the 19th district.

The district became obsolete following the2020 United States census.^[4] Following the reapportionment process after the 2020 census, New York came just 89 people short of retaining its 27th congressional district. The 435th seat instead went toMinnesota. The district was eliminated after the2022 midterm elections. Most of its territory close to Buffalo was merged with the 23rd district, while the portion close to Rochester joined the 24th district.
