The Andrew W. Mellon Foundation, commonly known as the Mellon Foundation, is a New York City-based private foundation with wealth accumulated by Andrew Mellon of the Mellon family of Pittsburgh, Pennsylvania. It is the product of the 1969 merger of the Avalon Foundation and the Old Dominion Foundation. These foundations had been set up separately by Ailsa Mellon Bruce and Paul Mellon, the children of Andrew Mellon.
The foundation is housed in New York City in the expanded former offices of the Bollingen Foundation, another educational philanthropy once supported by Paul Mellon.
In 2004, the foundation was awarded the National Medal of Arts.
