Tierney Gearon (born 9 September 1963) is an American photographer who came to prominence in Britain after a media controversy over her work at the Saatchi Gallery. She was born in Atlanta, Georgia. She had no formal art training, but studied ballet in Utah, where a European model agency saw her. This led to five years of modelling and travelling the world. During this time she took up photography herself. A Paris agent saw some of her Polaroid photos and encouraged her to do more work.
