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.

This was the first season following the RFU Adult Competition Review. The league was substantially similar to Yorkshire 3 with teams ranked 4th to 12th returning (1st to 3rd were 'promoted' to Counties 2 Yorkshire and the bottom two 'relegated' to Counties 4 Yorkshire) and supplemented by top 2 from Yorkshire 4 and one coming down from Yorkshire 2 so with five departing but only three arriving the league was reduced from 14 teams to 12.
