The 1951 National Trophy (sponsored by the Daily Mail) was the 14th edition of the Knockout Cup. The Trophy consisted of three stages; stage one was for the third division clubs, stage two was for the second division clubs and stage three was for the top tier clubs. The winner of stage one would qualify for stage two and the winner of stage two would qualify for the third and final stage. Exeter won stage one and therefore qualified for stage two.
