The 2012–13 IFA Championship (known as the Belfast Telegraph Championship for sponsorship reasons) was the fifth season since its establishment after a major overhaul of the league system in Northern Ireland. The season began on 10 August 2012 and ended on 4 May 2013. From next season onwards, the league would be operated by the Northern Ireland Football League, which was taking over from the Irish Football Association (IFA) for the 2013–14 season.
