Azcárraga is a surname of Basque origin. Nowadays, it is held by families not only in Spain, but also in Mexico, and other countries as well.
Azcárraga (spelled Azkarraga in modern Basque orthography) derives from the Basque word azkar meaning "maple", and the suffix -aga meaning "place, abundance" [1]; derivations with this suffix are common in Basque surnames. Another surname with a similar origin and meaning is Azcarreta [2], from the same root but with the ending -eta, another common Basque suffix meaning "abundance, plurality".
