Christopher O’Doherty, also known by the pseudonym Reg Mombassa, is a New Zealand-born Australian artist and musician. He is a founding member of the band Mental As Anything and member of Dog Trumpet (alongside his brother Peter O’Doherty).

Mombassa’s has two distinctive artwork styles. One style is his cartoonish designs he does for Mambo where he incorporates religious, political and popular culture themes. The other style is his highly sort after landscapes and portraits, many of which are inspired by his childhood in New Zealand. His artworks can be found in the Art Gallery of New South Wales, the National Gallery of Australia and other important regional galleries. Patrick White, Elton John and Ewan McGregor have all famously purchased his work.
