Glenalbyn, Georgian house in Stillorgan, Ireland.

Glenalbyn is a Georgian house built around 1810 in Stillorgan, County Dublin, now part of the Kilmacud Crokes GAA clubhouse complex. The main building has a west wing opened on 7 July 1996, with dressing rooms and a gym on the ground floor and a bar on the first floor overlooking tennis courts. The grounds, named Páirc De Burca, cover 6.5 acres.

The house was built around 1810 by paper merchant George Tinkler under the original name Janeville House. It received its current name, Glenalbyn, in 1883 and eventually became a sporting facility serving the local community.

The house has been the base of Kilmacud Crokes GAA club since 1965, and the club's grounds, bought in 1963 and named Páirc De Burca on 4 May 1964, host the All Ireland 7 a side Championships each September. The club counts over 5,000 members, and Glenalbyn also houses tennis, snooker and waterpolo clubs, the waterpolo side fielding senior ladies, under-15 and under-13 teams.

The property is located roughly 11 kilometers south of Dublin city center and features well-maintained outdoor sports courts. Access to the grounds is straightforward, and the site includes covered facilities for dining and leisure activities.

The grounds once housed a 33-meter public swimming pool that operated until December 2013 before closure. Today, six professional-standard tennis courts have become the defining feature of the property's sporting role.
