The 1970 All-Ireland Intermediate Hurling Championship was the tenth staging of the All-Ireland Intermediate Hurling Championship since its establishment by the Gaelic Athletic Association in 1961.

Kildare were the defending champions, however, they availed of the right to promotion and contested the All-Ireland Senior Hurling Championship.

The All-Ireland final was played at Croke Park in Dublin on 4 October 1970 between Antrim and Warwickshire, in what was their first ever meeting in the final. Antrim won the match by 4-18 to 3-06 to claim their first ever All-Ireland title.
