The 2013 Setanta Sports Cup was the eighth staging of the Setanta Sports Cup, an annual football competition featuring clubs from Northern Ireland and Republic of Ireland. It commenced on 11 February 2013 and ended on 11 May 2013 with the final played at the Tallaght Stadium, Dublin.
Crusaders were the defending champions, after they defeated Derry City 5–4 on penalties in the 2012 final, when the match ended 2–2 after extra time. However, this season they went out 4–1 on aggregate in the quarter-finals to Cork City. Shamrock Rovers were the eventual winners for the second time overall, following a comfortable 7–1 win over Drogheda United in the final. This season's competition was notable for the fact that all four semi-finalists represented the Republic of Ireland. It was also the sixth time in the eight competitions played thus far that the winner had been a League of Ireland club.
