Collectors Club of New York

The Collectors Club, often referred to as the Collectors Club of New York, is a private club and philatelic society in New York City. Founded in 1896, it is one of the oldest existing philatelic societies in the United States. Its stated purpose is "to further the study of philately, promote the hobby and provide a social, educational, and non-commercial setting for the enthusiastic enjoyment of our common passion".

From 1939 to 2023, the club was located at 22 East 35th Street between Madison and Park Avenues in the Murray Hill neighborhood of Manhattan, where it maintained a philatelic library of approximately 150,000 volumes available for research or study by scholars, historians, and philatelists. The building had originally been the house of Thomas and Fanny Clarke and was built in 1901–02, designed by the firm of McKim, Mead & White, with Stanford White as the partner in charge. The architecture is a combination of Colonial Revival style with medieval-inspired windows which recall those of Richard Norman Shaw, the avant-garde British architect of the late 19th century.

The building was purchased by the Collectors Club in 1937, and was designated a New York City landmark on September 11, 1979. It was sold in 2022 to the Republic of Serbia.

The Collectors Club Philatelist, published by the club since 1922, is currently published bi-monthly and contains scholarly articles on philatelic subjects.
