Thérèse Oulton (born 1953) is an English painter.
Born in Shropshire, Oulton studied in the late 1970s at Saint Martin's School of Art before going on to the Royal College of Art.
Oulton's work is essentially abstract though her early work often resembles rocky landscapes. Later works, often executed in a thick impasto, are abstract compositions with complicated and carefully worked surfaces.
A number of Oulton's later works use multiple repeated images, often with slight variations between the repetitions.
In 1987, Oulton became one of the first women artists nominated for the Turner Prize. She is represented by the Marlborough Gallery.
Her work is included in several public collections including Dallas Museum of Art, Metropolitan Museum of Art, Tate Gallery, UK Government Art Collection and the British Council Art Collection.
