The 1903 All-Ireland Senior Football Championship was the 17th staging of Ireland's premier Gaelic football knock-out competition.

In the Leinster Quarter final Kildare ended Dublin's period as All Ireland champions.

Kerry won their first football All-Ireland.

The four champions play in the "Home" championship, with the winners of the Home final going on to face London in the All-Ireland final.

A replay was ordered due to a disputed disallowed Kilkenny point.
