The van Ameringen Foundation is a private grant making foundation located in New York City. The Foundation was established by Arnold Louis van Ameringen in 1950 and received its assets from him during his lifetime and at his death in 1966 and from his widow, Hedwig van Ameringen, during her lifetime and at her death in 1996. This is not to be confused with the H. van Ameringen Foundation, established by Henry van Ameringen.

From its beginning, the Foundation has funded prevention, education, and direct care in the mental health field, with an emphasis on those individuals and populations having an impoverished background and few opportunities, for whom appropriate intervention would produce positive change.
