The 1912–13 Yorkshire Cup was the eighth occasion on which the Yorkshire Cup competition, a Rugby league tournament, was held. This year's tournament saw a new name on the trophy, Batley winning the trophy by beating Hull F.C. by the score of 17-3
This was the only time between 1909–10 and 1919-20 inclusive that Huddersfield would not contest the final. During this period the club made seven appearances out of the eight occasions winning six times (which included four consecutive times between 1913–14 and 1919–20.)
Background
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 thirteen.
This in turn resulted in three byes in the first round.
