1951–52 South Africa rugby union tour of Europe

In 1951-52 the South Africa national rugby union team toured England, France, Ireland, Scotland, and Wales, playing a series of test matches, as well as games against club, regional, and representative teams. South Africa accomplished their third Grand Slam by winning all four tests against the Home Nations sides, and also won the test match against France. This was the sixth South Africa tour and the fourth tour of the Northern Hemisphere. It was also the first time the South Africans played the invitational British Barbarian team.

The tour was the most successful the South African team had undertaken; the team only lost a single match. In the tests played the team beat all four Home Nations, France and the Barbarians. The only team to beat the Springboks was the invitational London Counties team. The final tour record saw 31 matches played, with South Africa winning 30 and losing just the one game.
