The Polish Genealogical Society of New York State (PGSNYS) was established in 1988 and is a not-for-profit, 501(c)(3) membership organization dedicated to helping its members and others in the community research their Polish roots, primarily in the Buffalo and Western New York area.

The Society collects and preserves documents and other resources of Polish genealogical, historical, and cultural significance, and seeks to collaborate with other local genealogical Societies, as well as organizations with a focus on Polish heritage.
