The Irish Football Association Challenge Cup (also known as the Tennent's Irish Cup for sponsorship purposes) is the national football knock-out cup competition in Northern Ireland. Inaugurated in 1881, it is the fourth-oldest national cup competition in the world. Prior to the break-away from the Irish Football Association by clubs from what would become the Irish Free State in 1921, the Irish Cup was the national cup competition for the whole of Ireland. Glenavon are the current holders after beating Linfield 2–0 in the 2016 final.
Since December 2015, the cup has been sponsored by Tennent's Lager – the competition's first title sponsor since 2012. It was previously sponsored by Nationwide Building Society, Bass Ireland Ltd and JJB Sports. 129 clubs entered the 2015–16 competition.
