Snyder (originally Snyderville) is a hamlet within the town of Amherst in Erie County, New York, United States that is part of the Buffalo – Niagara Falls metropolitan area. The hamlet was established in 1837. It was named for Michael Snyder, its first postmaster, who also operated a store at the corner of Harlem Road, which is also known as New York State Route 240, and Main Street, which is also known as New York State Route 5. The hamlet blossomed due to retail activity demand created along the Main Street transportation route between Buffalo and points to the east in the 19th and early 20th century.

As of 2009, the hamlet has several commercial districts, including a modest business district along Main Street that includes the original town focal point at Main Street and Harlem Road, and several educational institutions. The educational institutions are both public and private and range from kindergarten through college. The Snyder community has above-average affluence and education compared to the Buffalo region. The hamlet also hosts two structures listed on the National Register of Historic Places that serve as architectural artifacts of the early residential developments in the hamlet.

The traditional definition of the hamlet is the “Snyder” postal service area, now merged into the 14226 zip code. However, using United States Census Bureau-based data, which does not necessarily align exactly with the old postal boundaries, the modern definition includes parts of the neighboring Eggertsville hamlet.
