Patchogue-Medford Library, Public library in Suffolk County, New York, United States

The Patchogue-Medford Library occupies a converted department store on East Main Street and serves residents of the surrounding school district. The building houses collections of books, digital resources, and spaces designed for different activities and learning.

The facility was founded in 1883 as the Patchogue Library Association and later received financial support for new buildings in the early 1900s. This growth established its role as an educational center for the region.

The library's name traces to the Patchogue Library Association of 1883, and it took its present name in 1973 by state charter amendment after Patchogue and Medford school districts combined in 1951. Alma Custead served as librarian from 1914 to 1945. In 2000 the library marked its first 100 years under state charter, noted in a New York Times article.

The library sits at 54-60 East Main Street in Patchogue, in a former W.T. Grants department store it has occupied since 1981. It serves residents of the Patchogue-Medford School District, and a Neighborhood Center at Eagle Elementary School in Medford provides a study space and fiction collection. As Suffolk County's designated Central Library, it handles interlibrary loan and system-wide reference services.

The library has occupied a former W.T. Grants department store at 54-60 East Main Street since 1981, after 73 years in its Carnegie building on Lake Street. The Carnegie building was dedicated on March 4, 1908, on land given by Edwin Bailey, Sr.
