The 2016–17 Irish Cup (known as the Tennent's Irish Cup for sponsorship purposes) was the 137th edition of the Irish Cup, the premier knock-out cup competition in Northern Irish football since its introduction in 1881. The competition began on 19 August 2016 and concluded with the final at Windsor Park on 6 May 2017.

Glenavon were the defending champions, after they lifted the cup for the seventh time by defeating Linfield 2–0 in the 2016 final. They were eliminated at the semi-final stage. The competition was won by Linfield, who defeated Coleraine 3-0 in the final.

Format and schedule
126 clubs entered this season's competition, a decrease of three clubs compared with the 2015–16 total of 129 clubs. 12 members of the NIFL Premier Intermediate League and 90 regional league clubs from tiers 4–7 in the Northern Ireland football league system entered the competition in the first round, 26 of whom received a bye to proceed directly into the second round as necessitated by the number of participants. These clubs contested the first four rounds, with the eight surviving clubs joining the 24 senior NIFL Premiership and NIFL Championship clubs in the fifth round. Extra time was utilised to decide the victor in any games that remained tied after 90 minutes, with a penalty shootout following if required.
