The 1890 All-Ireland Senior Football Championship was the fourth staging of Ireland's premier Gaelic football knock-out competition. Previous years All Ireland champions Tipperary didn't take part in the Munster championship cancelled game against Clare. Cork were the champions.
From 1887 until 1891 the club champions represented the whole county.
Galway were the only entrants, so they received a bye to the All-Ireland semi-final.
