The 2009–10 All-Ireland Senior Club Football Championship was the 40th staging of the All-Ireland Senior Club Football Championship since its establishment by the Gaelic Athletic Association in 1970-71. The competition began on 18 October 2009 and ended on 17 March 2010.
The defending defending champion was Kilmacud Crokes; however, the club did not qualify after being beaten by Ballyboden St Enda's in a semi-final replay of the 2009 Dublin County Championship.
On 17 March 2010, St Gall's won the competition following a 0-13 to 1-5 defeat of Kilmurry-Ibrickane in the All-Ireland final at Croke Park. It remains their only championship title.
C. J. McGourty of the St Gall's club was the competition's top scorer with 2-28.
