The Columbia University Club of New York is a private university alumni club that extends membership to all graduates and their families of all the schools and affiliates of Columbia University, as well as Columbia undergraduate students, graduate students, faculty and administrators.

[1] Members benefit from numerous business and professional opportunities,[2] lectures and social events, and use of the Penn Club of New York's clubhouse at 30 West 44th Street in Midtown Manhattan where it is in residence.

The Penn Club facilities contain a lounge, business center, library, bar, formal and casual dining rooms, conference and meeting rooms, event rooms, overnight guestrooms, a complete athletic facility, and reciprocal use[3] of various clubs throughout the world.

By the early 1970s, in need of capital, and down to less than 500 members, it sold the building to the Unification Church of the Rev.

Membership at the Columbia University Club is open to all alumni and their families of all the schools and affiliates of Columbia University, as well as undergraduate students, graduate students, faculty and administrators.
