DIMIN is a contemporary art gallery located in the Tribeca neighborhood of New York City. The gallery was founded in 2023 by gallerist Robert Dimin and artist Justine Hill.

DIMIN is led by Robert Dimin who brings his idiosyncratic energy and passion to all gallery relationships from artists, to collectors, to historians, and art novices.
