Vasilius Origin and Meaning

The name Vasilius is a boy's name.

Vasilius is a masculine name with ancient Greek origins, serving as a variant of Basil or Vasilis (Βασίλειος). The name derives from 'basileus' meaning 'king' or 'royal,' carrying connotations of nobility and leadership. Throughout Orthodox Christian countries, particularly in Greece, Russia, and other Eastern European nations, variations of this name have been historically popular, often associated with Saint Basil the Great, a significant 4th-century theologian. Vasilius is a less common form that maintains the regal etymology while offering a distinctive, classical sound. Though rare in Western countries, it appeals to parents seeking a name with historical depth, royal associations, and a commanding presence while honoring Eastern European or Greek heritage.
