Kilkeel High has a successful
hockey team and the school fields teams in competitions from U-13 to an U-18 1st XI. Despite being a state comprehensive school, it competes in cup competitions dominated by the powerhouse grammar schools in Ulster, and the school regularly qualifies for the "All-Ireland" schools hockey tournament. In 2001 the boys 1st XI reached the final of the prestigious
McCullough Cup and despite a brave performance, they eventually lost in a
penalty shoot-out. Kilkeel High school also competes at
rugby. All age groups in the school also compete locally at football. The rugby team reached the high schools cup semi-final in which they played against 5 mile town. The team was beaten narrowly due to refereeing errors. Pupils from the school regularly qualify for County and "All-Ireland" athletics events including cross-country which the school has experienced great success in, in recent years. ==Other competition==
