Ondrej is Czech, Slovak in Origin.
Ondrej is the standard Slovak form of Andrew, from Greek Andreas, derived from anēr/andros “man; manly,” often interpreted as “strong, brave.” In Czech it appears as Ondřej (with the distinctive ř), and outside Central Europe the diacritics are frequently dropped to Ondrej. The name spread with Christianity through the veneration of Saint Andrew the Apostle, anchoring it in Central and Eastern European naming traditions.
Documented in Slovak records from the medieval period onward, Ondrej has remained a steady classic and is tied to St. Andrew’s Day (30 November) in regional calendars. Related forms include Andrej (Slavic), Andrew/Andy (English), Andreas (German/Greek), André (French), Andrés (Spanish), Andrzej (Polish), Andrei/Andrey (Russian/Romanian), Andriy (Ukrainian), András (Hungarian), and Anders (Scandinavian). Common diminutives are Ondro and Ondrejko in Slovak, and Ondra or Ondrášek in Czech. Feminine counterpart: Andrea.
