Neil Gallagher (born 18 August 1982) is an Irish former Gaelic footballer who played for Glenswilly and the Donegal county team.

Gallagher's haul of Ulster SFC titles was a joint county team record (alongside such past players as Anthony Molloy, Martin McHugh, Joyce McMullan and Donal Reid) for four years until Patrick McBrearty, Neil McGee, Paddy McGrath, Leo McLoone, Frank McGlynn, Michael Murphy and Anthony Thompson surpassed it in 2018.

[6] He won his second Donegal Senior Football Championship with Glenswilly in 2013, scoring a goal in the final against Na Cealla Beaga.

Donegal reached the 2006 Ulster Senior Football Championship Final and he played in that match at Croke Park.

[15] Alongside Glenswilly teammate Ciaran Bonner, he was dropped by manager John Joe Doherty over a breach of discipline ahead of the 2009 All-Ireland SFC qualifier game against Carlow.

The best performance of his career with Donegal came against Cork at Croke Park in the All-Ireland semi-final; indeed, it is widely regarded as one of the all-time best in team history.

[17] He scored a point against Mayo in the 2012 All-Ireland Senior Football Championship final, as Donegal claimed the Sam Maguire Cup.

[28] Less than a week after the 2014 All-Ireland Senior Football Championship final, Gallagher attended the 2014 Ryder Cup in Perthshire, Scotland.
