Clonkeen College is a Christian Brothers secondary school for boys in south Dublin, which opened links with charities and the developing world.

The Ordnance Survey Ireland map 1837–1842 shows Clonkeen School Ho[use],[1] located in the present day Cornelscourt Village.

Classes have visited Greece, the Aran Islands, Paris, Venice, Madrid, Barcelona, Amsterdam and Lake Garda.

During the year the students have the opportunity to do courses such as: Self-defense, ECDL, Gaelic football, FAI coaching, and Sailing.

New subjects in the transition year are cooking, music, effective communication, German, Japanese and technical drawing.

Students visit educational and historical sites like Christchurch,[clarification needed] St Patrick's Cathedral, Dublin, and Glendalough, Croke Park, Kilmainham Gaol and the National Art Gallery.

Since its inception, the Clonkeen College Student Council has shown a large involvement in the running of the school.

In the past they have had water fountains installed in the junior and senior corridors; more recently they had formal shoes and school jackets introduced to the uniform.

1st, 2nd and 3rd year students take part in the Dublin junior match play golf competition.

Every year students are accompanied by several teachers on an outdoor pursuits week in the Ardèche region in Southern France.
