The 2009 All-Ireland Senior Football Championship was the inter-county Gaelic football tournament played between 31 counties of Ireland, London and New York.

The draw for the 2009 championship took place on 9 October 2008.

The 2009 All-Ireland Senior Football Championship Final took place on 20 September 2009, contested by Cork and Kerry.

This was the year Tadhg Kennelly made history by becoming the first person to ever hold AFL Premiership and All-Ireland winning medals in the sports of Australian rules football and Gaelic football—he previously won the biggest prize in Australian rules with Sydney Swans in 2005.

A draw was made for round 4 of the qualifiers, with the winners of round three (Donegal, Kerry, Meath and Wicklow) playing against the losing provincial finalists (Antrim, Galway, Kildare and Limerick).
