Juncker was born in Redange, Luxembourg, and spent the majority of his childhood in Belvaux. He studied at the Roman Catholic "école apostolique" (secondary school) at Clairefontaine on the edge of Arlon in Belgium, before returning to Luxembourg to study for his Baccalaureate at the Lycée Michel Rodange. He joined the Christian Social People's Party in 1974.[9] He studied Law at the University of Strasbourg, graduating with a Masters in Law in 1979, and although he was sworn into the Luxembourg Bar Council in 1980, he never practised as a lawyer.
Juncker is fluent in his native language of Luxembourgish, along with French, German, and English.[10]
