Bernard Turnbull (16 October 1904 – 7 April 1984) was a Welsh international centre who played club rugby for Cardiff and was capped six times for Wales.
Turnbull played rugby as a boy for St. Peters RFC, one of the smaller teams based in Cardiff, along with his brothers, Maurice and Kevin.
Bernard Turnbull was first selected to play for Wales against Ireland in the 1925 Five Nations Championship under the captaincy of Idris Jones.
Turnbull turned out with his brother Maurice and fellow Welsh internationals Ronnie Boon, Archie Skym and captain Harry Bowcott.
Although Cardiff lost, sports journalist 'Old Stager' said: "B. R. Turnbull was the best centre on the field, ubiquitous in defence and valiant in attack.
