The 2002–03 All-Ireland Senior Club Hurling Championship was the 33rd staging of the All-Ireland Senior Club Hurling Championship, the Gaelic Athletic Association's premier inter-county club hurling tournament.
The championship began on 20 October 2002 and ended on 17 March 2002.
[1] On 17 March 2003 Birr won the championship following a 1–19 to 0–11 defeat of Dunloy in the All-Ireland final.
Athenry's Eugene Cloonan was the championship's top scorer with 4-23.
The build-up to the opening of the championship was dominated by Birr and the possibility that they would retain their All-Ireland title and lead the all-time club roll of honour with four championships.
