Philip Francis Stephanoff, sometimes Francis Philip Stephanoff was an English painter.

He was born in Brompton Row, London. His father, Fileter N. Stephanoff, was a Russian who settled in England and worked painting ceilings and stage scenery, until he committed suicide around 1790; his mother Gertrude Stephanoff (died 7 January 1808) was a flower-painter with Sir Joseph Banks as patron. James Stephanoff (1788?–1874), also an artist, was his elder brother.

Stephanoff became a popular painter of historical and domestic subjects, working both in oils and watercolours. He exhibited at the Royal Academy and British Institution from 1807 to 1845, and with the Old Watercolour Society from 1815 to 1820.

His wife, Selina Roland, died suddenly. Stephanoff ceased to work as artist many years before his own death, which occurred at West Hanham, near Bristol, on 15 May 1860.
