Glencorse Barracks is a British Army barracks situated in Glencorse just outside the town of Penicuik in Midlothian, Scotland. It is one of the three barracks which make up the City of Edinburgh Garrison, with Dreghorn and Redford Barracks. It has been the home for The Royal Highland Fusiliers, 2nd Battalion, The Royal Regiment of Scotland since 2006.

The regimental depot of a regiment is its home base for recruiting and training. It is also where soldiers and officers awaiting discharge or postings are based and where injured soldiers return to full fitness after discharge from hospital before returning to full duty. Normally, a variety of regimental stores will also be kept at the depot. The regimental depot is not the same as the regimental headquarters, though in practice the two will often be co-located in the same place.
