Caecilius (Berber: ⴰⴽⵙⵉⵍ Aksel or Aksil, Latin: Caecilius, Arabic: Kusaila), his name means "leopard" in the Berber language, died in the year 690 AD fighting Muslim invaders, was a 7th-century Berber Christian king of the kingdom of Altava and leader of the Awraba tribe of the Imazighen and possibly Christian King of the Sanhadja confederation. He is known for prosecuting an effective Berber military resistance against the Muslim invasion of the Maghreb in the 680s.

Initially the Berber-Roman States were able to defeat the Umayyad invaders at the Battle of Vescera (modern Biskra in Algeria), that was fought in 682 AD between the Berbers of King Caecilius and their Byzantine allies from the Exarchate of Carthage against an Umayyad army under Uqba ibn Nafi (the founder of Kairouan). Uqba ibn Nafi had led his men in an invasion across North Africa, eventually reaching the Atlantic Ocean and marching as far south as the Draa and Sous rivers. On his return, he was met by the Berber-Byzantine coalition at Tahuda south of Vescera, his army was crushed and he himself was killed. As a result of this crushing defeat, the Arabs were expelled from the area of modern Tunisia and eastern Algeria for more than a decade.
