Larch Hill International Scout & Guide Centre is the national campsite and administrative and training headquarters of Scouting Ireland, founded in 1938.

It sits in the picturesque valley between Kilmashogue and Tibradden Mountains in Dun Laoghaire Rathdown, about 13 kilometres from Dublin city centre, on the edge of the Dublin/Wicklow Mountains.

The centre serves Beaver Scouts, Cub Scouts, Scouts, Venturers, and Leaders, and also accommodates Girl Guides, school groups, and youth organisations.

Facilities include Adirondack shelters sleeping eight people each, located in the forestry above the Dolmen Field. Scouting Ireland's national office is also based on the grounds.

The site has a long history of hosting national and international scouting events.
