1920 All-Ireland Senior Hurling Championship

The 1920 All-Ireland Senior Hurling Championship was the 34th staging of the All-Ireland hurling championship since its establishment by the Gaelic Athletic Association in 1887. The championship began on 9 May 1920 and ended on 14 May 1922.

Cork were the defending champions; however, they were defeated by Dublin by 4-9 to 4-3 in the final.

The final stages of the championship were delayed due to the ongoing War of Independence.

Teams
A total of fourteen teams contested the championship, the same as the previous championship; however, there were some changes of personnel, with Westmeath replacing Laois in the Leinster Senior Hurling Championship.

Miscellaneous

 * Not one of the Dublin hurling team that won the All-Ireland final was born in Dublin.
