Al-Mustazi is an impact crater located on the anti-Saturn hemisphere of Saturn's moon Enceladus. Al-Mustazi was first observed in Cassini images during that mission's March 2005 flyby of Enceladus. It is located at 20.8° South Latitude, 198.4° West Longitude, and is ten kilometers across. Cassini observed numerous southwest-northeast trending fractures cutting across the southwest rim of Al-Mustazi, forming canyons several hundred meters deep. These fractures were deflected by the weakened regolith produced by the Al-Mustazi impact.[1] This deflection produced the pattern of radiating fractures seen along the northeastern rim of Al-Mustazi.

Al-Mustazi is named after Az-Zahir, an 13th-century Abbasid caliph and a character in the "The Hunchback’s Tale" from The Book of One Thousand and One Nights.
