John Cuthbertson Entrican (24 September 1908 — 19 May 1985) was an Irish international rugby union player.
The son of a Presbyterian minister, Entrican was a Queen's University Belfast, Ulster and Ireland fullback.[1]
Entrican debuted for Ireland during the 1931 Five Nations Championship, deputising an injured James Egan at fullback for a match against Scotland at Lansdowne Road.[2] His performance received mixed reviews, but Ireland were able to secure a 8–5 win. This remained his only international appearance.[3]
