David Whitney (1939 – June 12, 2005) was an American art curator, collector, gallerist and critic. He led a very private life and was not well known outside the art world, even though he participated naked in the 1965 Claes Oldenburg happening Washes. He was the life partner of architect Philip Johnson (1906–2005) for 45 years until their deaths five months apart. He was also a close friend of Andy Warhol.
