The 1890 All-Ireland Senior Football Championship was the fourth staging of Ireland's premier Gaelic football knock-out competition. 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.
