Stephen O'Neill (born 19 November 1980) is an Irish former Gaelic footballer who played at senior level for the Tyrone county team.

Tyrone won the competition, but O'Neill refused to accept the medal, citing the fact that he felt he had not earned it, having not been part of the team on their journey to the final.

Following two years where he was blighted by recurring injuries, O'Neill agreed to undergo surgery before the end of 2007 to resolve a complex knee tendinitis condition.

[8] O'Neill's return to action came earlier than many expected during the 2008 All-Ireland Senior Football Championship Final, as a 25th minute sub for the injured Colm McCullagh.

Although he failed to register a score he caused the Kerry defence a number of problems and helped Tyrone to their third Senior Football Championship win in six years.

O'Neill helped Tyrone win another Ulster Championship in 2009, beating Antrim in the final, collecting an end of season All Stars Award, his third.
