Niall O'Donnell (born 1998) is an Irish Gaelic footballer who plays for St Eunan's and the Donegal county team.
The Irish Independent's Colm Keys named O'Donnell among his "18 for [20]18: The brightest young talents" in Gaelic football, describing him as "both elusive and skilful".
[3][4] In 2016, following his Ulster minor title with Donegal, he became the eighth student from the school to win an Ulster Colleges All Star, succeeding — among others — Michael Murphy and Shaun Patton; O'Donnell played alongside Patton in the school team.
[11] He captained his club to the 2021 Donegal Senior Football Championship, aged 23, scoring three points in the final.
He played against Kerry as a half-time substitute in the opening fixture of the 2018 National Football League at Fitzgerald Stadium.
[19] He did not feature on the pitch when Donegal won the 2018 Ulster Senior Football Championship,[20][21][22][23] as, alongside Jason McGee, he had decided to drop down to play with the under-20 team instead.
[49] In the 2022 Ulster Senior Football Championship, O'Donnell made substitute appearances in each of Donegal's three fixtures, the quarter-final against Armagh, the semi-final against Cavan and the final against Derry (which included extra-time, during which he played).
[50][51][52] He made a late substitute appearance in the 2022 All-Ireland Senior Football Championship qualifier loss to Armagh, during which he scored a point.
