Frans Herman ten Bos (21 April 1937 – 1 September 2016) was a Scottish rugby union footballer. He played for Scotland as a lock in the 1960s, and was capped seventeen times. Ten Bos attended Fettes College in Edinburgh, where he was introduced to the game, and later played for Oxford University RFC and London Scottish FC. Notably, ten Bos scored a try against Wales in Cardiff, in the 1962 match there, which resulted in Scotland's first victory against Wales in an away game in thirty five years; the score was 8-3 to Scotland. Scotland later won the game 11-6, rare for an away game.
