The 1887 All-Ireland Senior Football Championship is the first edition of GAA's premier inter-county Gaelic football tournament, played between 12 counties of Ireland. The tournament featured club teams who represented their respective counties after their county championship. The 21 a-side final was between Commercials of Limerick and Young Irelands of Louth. The final was played in Beech Hill, Donnybrook on April 29, 1888, with Commercials winning by 1-4 to 0-3. Unlike later All-Irelands, there were no provincial championships and it was an open draw.
