Reginald "Reg" Earl Campbell (2 March 1923 – 30 May 2008) was an Australian portrait painter and self-taught artist.

He served as a private in the General Transport Company in New Guinea and was discharged in 1945.

[2] After military service, Campbell moved to Bathurst, New South Wales in the 1950s, working initially as a signwriter,[2] and later moved to live in a peaceful rural setting, outside Bathurst, where he established his gallery and completed some of his most accomplished portraits.

Lesser-known works are the portraits that Campbell painted of two other personalities of his generation, a young radio broadcaster John Laws and the television games show personality, Bob Dyer.

Testimony to his mastery are the commissions to paint the portraits of many prominent figures in Australia and overseas including approximately 100 knights of the realm, 23 vice regal portraits in Denmark, nine bishops and archbishops and hundreds of other famous personalities including Don Bradman, Albert Namatjira and Sir Garfield Barwick.
