The 2005 Croke Cup was the 54th staging of the Croke Cup since its establishment by the Gaelic Athletic Association in 1944.
St Kieran's College were the defending champions.[1] [2] The introduction of a "back door system" allowed the defeated Leinster and Munster finalists entry into the All-Ireland series for the first time.[3]
The final was played on 2 May 2005 at Semple Stadium in Thurles, between St Flannan's College and St Kieran's College, in what was their 10th meeting in the final overall and a first meeting in the final in five years.[4] St Flannan's College won the match by 2–15 to 2–12 to claim their 14th Croke Cup title overall and a first title in six years.[5] It remains their last All-Ireland title.
