This is a list of sports people who have played both cricket and rugby union at a high level. First-class or List A cricket, provincial rugby and international cricket or rugby are considered to be high level for the purposes of this list. To be eligible, players must have appeared for their country's national side in at least one of the sports. The lists below are alphabetical and sorted by the country in which the player spent their international career.

Alfred Shaw and Arthur Shrewsbury, who organised the first British Isles rugby tour to Australasia in 1888 were also noted cricketers.

While the Wales national rugby union team is a force in international rugby, the Wales national cricket team plays only rarely, and the nation of Wales is usually subsumed under England for cricketing purposes.

Both Irish rugby players and cricketers, unlike soccer players, also play as one nation.

The two sports have also had a considerable overlap in commentators and journalists, e.g. Robert Hudson, Howard Marshall, Lisa Olson, Denzil Batchelor, Ian Smith, Steve James, Allan Massie

Many venues, including St. Helen's Rugby and Cricket Ground, Carisbrook, Eden Park, Raeburn Place, Headingley Stadium, Sydney Cricket Ground, McLean Park, The Oval, Cardiff Arms Park and Limavady Cricket and Rugby Club have been used for both rugby and cricket over the years.

Due to the historical relationship between rugby league and rugby union, several of these players have also competed in high level rugby league as well. (See List of cricket and rugby league players)
