The 1910 British Isles tour to South Africa was the eighth tour by a British Isles rugby union team and the fourth to South Africa.

As well as South Africa, the tour included a game in Bulawayo in Rhodesia, now Zimbabwe.

Led by Ireland's Tommy Smyth and managed by Walter E. Rees and W Cail the tour took in 24 matches.

The British Isles team lost two and won one test match against the Springboks.

Seven players from Newport RFC were selected for the tour which was for a time the record for players selected from one club for a British Lions Tour.
