New York's 2nd State Senate district is one of 63 districts in the New York State Senate. Since 2021, it has been represented by Republican Mario Mattera, who succeeded former Senate Majority Leader John Flanagan. For the 2022 election, the 2nd district was redistricted from the old 2nd district and the 5th district.
2nd District covers north-central Suffolk County on Long Island, including the town of Smithtown, as well as portions of Brookhaven and Huntington.
The district overlaps with New York's 1st and 3rd congressional districts, and with the 3rd, 4th, 5th, 8th, 10th, and 12th districts of the New York State Assembly.
