Counties 3 Yorkshire, previously known as Yorkshire 3, is an English rugby union league at the ninth tier of the domestic competition. Club rugby in Yorkshire operates without promotion play-offs meaning that the top two teams are automatically promoted to Counties 2 Yorkshire and the bottom two teams are relegated to Counties 4 Yorkshire. Each season a team from Counties 3 Yorkshire or Counties 4 Yorkshire may be picked to take part in the RFU Junior Vase - a national competition for clubs at levels 9–12.
