Abu Laith al-Libi (Arabic: أبو الليث الليبي, b. approx. 1967 – d. January 29, 2008, Mir Ali ) was a senior leader of the al-Qaeda movement in Afghanistan who appeared in several al-Qaeda videos. He was believed to have been active in the tribal regions of Waziristan. He also served as an al Qaeda spokesman. According to the Defense Intelligence Agency, he was an "expert in guerilla warfare."

The Defense Intelligence Agency says he was 41 at the time of his death, putting his birth date around 1967. In the 1980s he was one of the Afghan Arabs who came to Afghanistan to fight the Soviet Union during the Soviet-Afghan War. He returned to Libya in 1994 and took part in a failed attempt to oust Muammar al-Gaddafi. In the wake of this attempt al-Libi escaped to Saudi Arabia, where he was imprisoned in Riyadh following the Khobar Towers bombing. Sometime thereafter he was either released or managed to escape, and came to Afghanistan to collaborate with al-Qaeda and the Taliban. In 1997, a dispute between the the two oldest brothers of the Canadian Khadr family, Abdullah and Abdurahman, was mediated by al-Libi, who earned their confidence and respect telling them about Dubai and Ferarris, and they later referred to him as a "really cool" person. In 2002, he approached the father Ahmed Khadr about letting the 15-year old Omar serve as a translator for some Arab "visitors" in the region. When a gun-battle resulted in the young translator being sent to Guantanamo Bay, al-Libi tried to placate the family with gifts and apologies, but Khadr remained furious and refused to associate with al-Libi, whom he blamed for not taking care of his son.

In May 2005 when Abu Faraj al-Libbi was captured in Pakistan, his identity was confused in many reports with Abu Laith al-Libbi.
