Zveza ljudskih tradicijskih skupin Slovenije (skrajšano ZLTSS) deluje že od 70-ih let prejšnjega stoletja pod različnimi imeni. Po letu 1991 je Zveza dobila sedanje ime. ZLTSS je prostovoljna, samostojna, nepridobitna zveza festivalov in društev, folklornih skupin, ki se združujejo zaradi ohranjanja, prikazovanja in izvajanja ljudskih plesov, običajev, ljudskih oblačil, pesmi in glasbe. ZLTSS je član mednarodne organizacije CIOFF® (Conseil International des Organisations de Festivals de Folklore et d ‘Arts Traditionnels – Zveza organizacij folklornih festivalov in ljudske umetnosti), ki je član UNESCO-a (Organizacija Združenih narodov za vzgojo, znanost in kulturo). The Union of Slovene Folklore Groups is a voluntary, independent and non-profit union of registered associations, folklore groups and festivals which have come together to co-operate with folklore festival organisers both in Slovenia and abroad in the presentation of Slovene folkloric customs, music and dance. It offers assistance to members regarding event organisation and participation in festivals, circulates information about international events, connects different cultural organisations, and organises meetings and symposia at home and abroad in order to advance its professional work. The Union has an annual meeting and a board of professionals evaluates groups and offers professional assistance to them. The Union of Slovene Folklore Groups is a member of the International Council of Organisations of Folklore Festivals and Folk Art (CIOFF®).
