List of Galician words of Celtic origin

This is a list of Galician words of Celtic origin, many of them being shared with Portuguese (sometimes with minor differences) since both languages are from medieval Galician-Portuguese. A few of these words existed in Latin as loanwords from a Celtic source, usually Gaulish, while others have been later received from other languages, mainly French, Occitan, and in some cases Spanish. Finally, some were directly acquired from Gallaecian, the local pre-Latin Celtic language. Any form with an asterisk (*) is unattested and therefore hypothetical.

A systematic investigation of the Celtic words in Galician-Portuguese is still lacking.
