The Sri Lanka Girl Guides Association is the national Guiding organization of Sri Lanka. It serves 54,824 members (as of 2016). Founded in 1917, the girls-only organization became a full member of the World Association of Girl Guides and Girl Scouts in 1951. An overseas branch of the Sri Lanka Girl Guides Association operates at the Sri Lankan School in Muscat, Oman.
In 2009, Girl Guides at the Sri Lankan School in Muscat had their camp in October canceled to prevent the spread of Swine flu. The Guides paper recycling project was also discontinued for the same reason.
