The siege of Almeria was a successful attempt by the Almohads to capture the city of Almeria from the Christians in 1157, who had captured the city a decade ago. The Almohads expelled the Leonese and Genoese garrison and repelled a Castilian attempt to relieve it.

After the capture of Granada by the Almohads in 1156, they turned their eyes to capture the city of Almeria. The city had been under Christian control since 1147. The Christians decided to take advantage of the political turmoil in Andalusia and the fall of the Almoravid dynasty. They launched a Crusade against the city with land and naval forces.

The Castilian king, Alfonso VII, learned the news and hurried himself to relieve the besieged with an army of 12,000 knights supported by 6,000 Muslims of ibn Mardanīsh. During the siege, a quarrel between Abdullah bin Sulieman and Ahmed bin Milhan ended with Ahmed defecting to Ibn Madanish. The Almohad siege lasted for months, and the King's attempt to relieve the city was repelled. The King and Ibn Mardanish withdrew frustrated, leaving the city's fate to the Almohads. The garrison was exhausted so they surrendered in exchange for their lives which they agreed.^{[8][9][10][11]}
