Mark Lancaster (born 14 May 1938 in Holmfirth, West Yorkshire) is an English artist and set designer.
Mark Lancaster was born Christopher Ronald Mark Lancaster, but early in life he decided that "Mark" was his favorite of the three names. Educated at Holme Valley Grammar School, 1949–52, and Bootham School, York, from 1952 to 55, after which he worked in a family textile business and studied textile technology for six years, painting in his own time, before going to King's College, Newcastle in 1961 to study Fine Art. From 1961 to 1965 Mark Lancaster studied under Richard Hamilton at the University of Newcastle upon Tyne, where he also taught from 1965–66, and then at the Bath Academy of Art, Corsham, Wiltshire, 1966–68, while living in London. He first visited New York City in 1964, where he worked briefly as an assistant to Andy Warhol, appeared in several Warhol movies, and met Jasper Johns, Ray Johnson, Ellsworth Kelly, Roy Lichtenstein, Frank Stella, James Rosenquist, Larry Rivers, Frank O'Hara, Robert Motherwell, Helen Frankenthaler, Norman Mailer and many others. In New York he photographed extensively, and started a series of paintings related to the imagery of the Howard Johnson's restaurants, then ubiquitous, bringing back to England information and ideas, and giving a "New York" lecture and slide show with music that influenced artist friends at Newcastle, such as Bryan Ferry, Stephen Buckley, Nicholas deVille, Tim Head and Keith Milow.
