Xabi Aburruzaga (born 1978 in Portugalete, Euskadi, Spain) is a Basque musician and composer, who is a master of the Trikitixa, the diatonic accordion.

In 2002 he created a song of Bermeo celebrations, after which he published a new album with the collaboration of Mikel Urdangarin, Joseba Tapia and Iñaki Aurrekoetxea.

This led to his publishing another book and record, based on a song written by Faustino Arrola, adapting it to the new sounds of more modern music.

On this project, he collaborated with various artists such as Amaia Oreja, Mikel Markez, Leturia and Xabi Zeberio.

In 2009 he published an album with lyrics, Denboraren Naufragoa, with texts of Kirmen Uribe accompanying the music.
