The given name Xavier (/ˈzeɪviər, ˈseɪ-, ˈzævieɪ/, Catalan: [ʃəβiˈe, ʃaviˈeɾ, tʃaviˈeɾ], Galician: [ʃaˈβjeɾ], Portuguese: [ʃɐviˈɛɾ], French: [ɡzavje, ksavje]; Spanish: Javier [xaˈβjeɾ]; Basque: Xabier [ʃaβier])[1] is a masculine name derived from the 16th-century Navarrese Roman Catholic Saint Francis Xavier.

Xavier comes from the name of the Jesuit missionary saint Francis Xavier, where Xavier stands for his birthplace of Javier (Xabier in Basque; Xavier in Old Spanish) in the Kingdom of Navarre.

The toponym is itself the romanization of the Basque place-name (and surname) etxe berri, meaning 'castle', 'new house' or 'new home'.

[2][page needed][3] An increase in usage of the name in the United States has been attributed to the Marvel Comics character Charles Xavier, and the feature film version of that character played by Patrick Stewart.
