Ali Baba is a large crater in the northern hemisphere of Saturn's moon Enceladus. Ali Baba was first discovered in Voyager 2 images. It is located at 55.1° North Latitude, 22.3° West Longitude and is 39.2 kilometers across. It is located near the craters Aladdin and Samad. Ali Baba has a large dome in its interior, suggesting the crater has undergone viscous relaxation. The top of the dome even reaches higher than the crater rim.
