The Battle of Aqbat al-Bakr (2 June, 1010) wis a battle of the Fitna of al-Andalus that takes place in the area in and around Espiel, Spain, between the forces of the Caliphate of Cordoba, whose forces are commanded by Sulayman ibn al-Hakam, and the Muslim rebel forces of the Castilian-Andalusian alliance trying to overthrow their Caliph overlords under the command of Muhammad ibn Hisham, al-Tagr Al-Awsat and several Christian warlords including Ermengol I, Hugh I, and Ramon Borrell.

The two armies meet at Espiel on June 2nd, 1010 and the forces of the Caliphate of Cordoba are decisively routed, marking one of the first battles of the war and a significant gain for the rebel Castilian-Andalusian alliance.

Although this battle takes place in the general time frame of the Spanish Reconquista, it is not unusual for Christian and Muslim forces to join together to achieve common goals.
