(26 September 1823 - 31 July 1863) was an English portrait and genre painter.
Knight was born in Newbury, Berkshire where his father, John Knight, was a schoolmaster. He was to become a solicitor, but gave up his law studies after two of his paintings were accepted by the annual exhibition of the Society of British Artists. He moved to London in 1855, taking lodgings in Kennington Road, Lambeth, and supporting himself by drawing crayon portraits while studying in the British Museum and in the schools of the Royal Academy.
