Julen Agirrezabala Astúlez (born 26 December 2000) is a Spanish professional footballer who plays as a goalkeeper for La Liga club Athletic Bilbao.

Born in San Sebastián and raised in nearby Errenteria[1] (both in Gipuzkoa, Basque Country), Agirrezabala joined Athletic Bilbao's youth setup in 2018, from Antiguoko.

On his debut with the reserves on 1 November 2020, Agirrezabala started and saved a penalty kick in a 3–2 Segunda División B away win against Club Portugalete.

[7][8] He spent most of that season playing for the reserves, but was selected in the Copa del Rey in preference to Jokin Ezkieta (first-choice goalkeeper Unai Simón stepping aside) and took part in victories over Barcelona and Real Madrid before the run was ended at the semi-final stage by Valencia.

[10] Agirrezabala played every minute of Athletic's run in the 2023–24 Copa del Rey, keeping four clean sheets including in both legs of the semi-final against Atlético Madrid; in the final against RCD Mallorca, his solid performance was capped by saving Manu Morlanes's effort in the penalty shootout as the Basques claimed the trophy for the first time in 40 years.
