The 1980 All-Ireland Under-21 Hurling Championship was the 17th staging of the All-Ireland Under-21 Hurling Championship since its establishment by the Gaelic Athletic Association in 1964.
Tipperary were the defending champions.
On 14 September 1980, Tipperary won the championship following a 2-9 to 0-14 defeat of Kilkenny in the All-Ireland final.[1] This was their fourth All-Ireland title in the under-21 grade and their second in succession.
