Coolmine RFC, is located in the north west Dublin 15 area of Dubli, was first affiliated to the Leinster Branch – Irish Rugby Football Union in 1980 and entered the Junior Leagues in 1981.

The Mini Rugby Youths section was founded in 1980 and has prospered ever since in the Dublin 15 suburb of Co Dublin. In 1985, after a number of successful years on the playing fields, Coolmine purchased its current home, a site consisting of eight acres at Ashbrook, Castleknock, Dublin 15. A series of developments took place over the following years and the site now consists of two floodlit pitches, training area, car park and amodern two storey clubhouse which was officially opened in 1993 by the then President of Ireland, Mary Robinson.On the playing front, Coolmine has continued to prosper and the first XV currently competes in the Leinster League. The Under 20s compete in the J.P.Fanagan League and the youths from 7s-18s have their own Metropolitan League and Cup Competitions.

A selection of Cups and Pennants from the various sections adorn the upstairs bar area.While concentrating much on the playing front, Coolmine has not neglected the social aspect and as well as the mandatory trips to England, Scotland and Wales, it has undertaken tours to Italy, France and the Cayman Islands and Hong Kong. Teams at all levels regularly organise tours throughout the year.

In 2006, Coolmine completed an ambitious clubhouse renovation project which added two new changing rooms, shower areas and toilets, as well as an entrance atrium, committee room and viewing balcony over the main pitch. Our new clubhouse is also wheelchair accessible with a lift to the first floor.
