Concordia Language Villages (CLV), previously the International Language Villages, is a world-language and culture education program. Since beginning in 1961, it has grown to offer summer camp in 15 modern languages and school-year weekend programs mostly for Spanish, French, and German. Summer and winter programs are taught through a language and cultural immersion philosophy, which allows for experience-based learning. The Villages annually serves over 13,000 young people, aged 7–18, from every state of the US, as well as Canada and 31 other countries, and are sponsored by Concordia College of Moorhead, Minnesota, a private four-year liberal arts college of the Evangelical Lutheran Church in America.
