New York’s 24th congressional district is located in Upstate New York, stretching alongside Lake Ontario from near Buffalo in the west to Watertown in the east. The district does not include Rochester, which is in the 25th district. Since 2023, it has been represented by Claudia Tenney. In the 2022 election it voted more strongly Republican than any other district in the state. Prior to the redistricting which took effect in 2023, the district included the city of Syracuse.

In the 117th United States Congress, it was one of very few Democratic-leaning districts in the country to be represented by a Republican, and one of only nine districts that voted for Joe Biden in the 2020 presidential election while being held or won by a Republican. Katko had also won re-election in 2016 while the district was carried by Democrat Hillary Clinton.

Certain parties will invariably endorse either the Republican or Democratic candidate for every office, hence the state electoral results contain both the party votes, and the final candidate votes (Listed as "Recap").
