O'Connell's GAC, Tullysaran (Irish: Tulach Saráin[1]) is a Gaelic Athletic Association club in County Armagh, Northern Ireland.

The club's senior teams currently play Gaelic football in the Armagh Intermediate Championship and Division 2 of the All-County Leagues.

Tullysaran O'Connell's was one of the nine clubs represented at the first recorded meeting of Armagh County Board on 30 March 1889.

The Armagh Guardian of 20 May 1904 records a match being played at Kilmatroy near Tullysaran, but the club's own records date back only to 1932, referring not to the present name but to Knappagh O'Connell's or the Sons of O'Connor, Knappagh.
