Jack Deryck Erle Monteith (24 August 1922 — 26 June 1992) was an Irish rugby union international.
Monteith, a centre, played his rugby for Malone, Queen's University and Ulster.[1]
Capped three times by Ireland in the 1947 Five Nations Championship, Monteith debuted in a win over England at Lansdowne Road, then led the team for the next two fixtures, after incumbent captain Con Murphy was dropped from the side. These remained his only Ireland caps.[2]
Eldest son of a Ballymoney dentist, Monteith had one brother and four sisters.[3] He was a close friend in his later years of athlete Mary Peters.[4]
