The 1982 All-Ireland Under-21 Hurling Championship was the 19th staging of the All-Ireland Under-21 Hurling Championship since its establishment by the Gaelic Athletic Association in 1964.
Tipperary were the defending champions, however, they were beaten by Limerick in the Munster semi-final.
On 12 September 1982, Cork won the championship following a 0-12 to 0-11 defeat of GAlway in the All-Ireland final. This was their eighth All-Ireland title in the under-21 grade and their first in six championship seasons.
