The 1909–10 Yorkshire Cup was the fifth occasion on which the Yorkshire Cup competition, a Rugby league tournament, was held. This year's final was between two clubs who had not previously played in the final and Huddersfield won the trophy by beating Batley by the score of 21–0. The match was played at Headingley, Leeds, now in West Yorkshire. The attendance was 22,000 and receipts were £778. This was Huddersfield's first appearance in what would be seven appearances in eight consecutive finals between 1909 and 1919 (which included four successive victories and six in total.)
