The 1958 Yorkshire Cup was the fifty-first occasion on which the competition had been held.
Leeds won the trophy by beating Wakefield Trinity by the score of 24-20.
This season there were no junior/amateur clubs taking part, no new entrants and no "leavers" and so the total of entries remained the same at sixteen.
This in turn resulted in no byes in the first round.
