Johnny Mullagh was an Australian cricketer from Victoria who was the leading player on the famous 1868 Aboriginal cricket tour of England. He was a skilful all-rounder, being a right-arm bowler and right-handed batsman. In December 2020, Mullagh was inducted into the Australian Cricket Hall of Fame.

In 1868, a cricket team composed of Aboriginal Australians toured England between May and October of that year, being the first organised group of Australian sportspeople to travel overseas. It would be another ten years before an Australian cricket team classed as representative left the country.
