The Philanthropin (Greek for "place of humanity") is a Jewish elementary school and gymnasium in Frankfurt, Germany.
The school was supported financially by the government and was from the start also open to non-Jewish pupils.
The school became a prominent centre of liberal Judaism in the 19th century; many of its teachers were active in the Jewish reform movement.
The school experienced a new golden era during the Weimar Republic under the leadership of Otto Driesen [de].
The Philanthropin is a neighbour of the Musterschule, a noted progressive gymnasium, which is found on the other side of Eckenheimer Landstraße.
