The 1993 All-Ireland Under-21 Hurling Championship was the 30th staging of the All-Ireland Under-21 Hurling Championship since its establishment by the Gaelic Athletic Association in 1964.
Waterford were the defending champions, however, they were beaten in the Munster Championship.
On 3 October 1993, Galway won the championship following a 2-9 to 3-3 defeat of Kilkenny in a replay of the All-Ireland final. This was their sixth All-Ireland title in the under-21 grade and their first in two championship seasons.
