Julián Retegui Barbería, also known as Retegi II (born in Eratsun, Navarre, Spain on October 10, 1954) is an ex-player of Basque pelota.
On December 13, 1997 he won his last prize, the Basque Championship of 4½ against Titin III in the Ogeta Frontón of Gasteiz.
He played his last match on September 20, 2001, in the Adarraga frontón, Logroño, with Barriola against Olaizola II and Armendariz.
He debuted in the same town his father did, Zarauz, but in a different frontón called Aritzbatalde in July 2005.
From that day on he started his brilliant career, getting to the finals from 1980 to 1993, and winning the championship eleven times.
