The Battle of Walaja (Arabic: معركة الولجة) was fought in Mesopotamia in May 633 between the Rashidun Caliphate army under Khalid ibn al-Walid and Al-Muthanna ibn Haritha against the Sassanid Empire and its Arab allies.

Khalid defeated the Sasanian forces by using a variation of the double envelopment tactical manoeuvre, similar to the manoeuvre that Hannibal had used to defeat the Roman forces at the Battle of Cannae.
