The college has always placed a great emphasis on Gaelic Games since it was established in 1884. Well known Capuchins such as Fr.Nessan and Bro. Edward were prominent for many years in developing the college as a force in Gaelic Games. 1950 was a year of great success for the college winning the Corn an Fhriunnaigh (u 16), and in senior football we claimed the Corn Uí Mhuirí in Munster and the Simcox Cup in Cork .

The school played at a lower grade for a number of years due to small numbers and the loss of boarding pupils, however the commitment of the players never waned as playing for the school was always highly valued.

The college has gone from strength to strength in recent years with a growth in numbers and strong local clubs providing good players for College teams.

The present Corn Uí Mhuirí side hosts players from St. Michaels, Douglas, Nemo, St. Finbarrs, Carrigaline and Passage.

Great work has been done by teachers in the college in recent years. Wins in the Cork Colleges U-14 A (2010 and 2011), Senior B (2011), and Corn na gColaistí (Munster U-16 ) has raised the spirits in the college.

The U-15 team were narrowly defeated by Dingle in the final of the Corn Uí Mhoráin (A Munster) in November 2011.

The present Corn Uí Mhuirí team have already qualified for the quarter final of the competition beating St. Flannans College and Intermediate School Killorglin along the way.

It is great to see Rochestown College back in the big time in Gaelic football.  Gaelic football in the college is going from strength to strength and with hard work and commitment from all this will continue long into the future.
