Xerigordos, often incorrectly Xerigordon in modern historiography, was a castle in Anatolia that served as the setting of the Siege of Xerigordos as a part of the People's Crusade in 1096. The contemporary records assert that the fortress was located on a hill and its water supply came from both a water well and a spring just outside the walls. The exact location has not yet been identified. Albert of Aix wrote that it was about three miles away from Nicaea.
