List of Athletic Bilbao players

As of 2012, Athletic has played for 82 years in the Primera División, the top tier of Spanish football, and is one of only three clubs, the others being Real Madrid and Barcelona, never to have been relegated from La Liga.

The team of that period included the prolific goalscorer Rafael "Pichichi" Moreno; he scored the first goal in the San Mamés Stadium on 21 August 1913, scored a hat-trick in the 1915 Copa del Rey final, and his 89 games for the club produced a total of 78 goals.

Joseba Etxeberria, who joined Athletic from Real Sociedad in 1995 for a record transfer fee of €3 million,[10] is the player with the most appearances for the club in the last 30 years.

A statistical analysis by El Correo in 2023 showed that the more historic players at the top of the list had played many more minutes overall than those from the modern era with fewer or no substitutions available – Orúe was on the field for the entirety of all matches he played, with contemporaries Panizo, Gaínza and Canito not doing so only twice apiece, contrasting sharply with the likes of Muniain and Susaeta whose totals for coming on and coming off were each well into the hundreds.

Listed below are all the captains of Athletic Bilbao since football became professional in Spain with the introduction of La Liga in 1929.
