Guel's Dilanza (ディランザ グエル専用機 Diranza Gueru Sen'yō-ki?) is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury. It is piloted by Guel Jeturk.

Among the basic MS Dilanza units developed by Jeturk Heavy Machinery, a number have been customized for their pilots. One of these has been modified to suit the piloting style of Guel Jeturk, heir to the company. Its outward appearance has also been tailored to fit Guel's penchant for the ostentatious. Painted in a vivid magenta and fitted with a decorative headpiece, this unit embodies the skill and unshakable self-confidence which made Guel, Asticassia's best pilot. It gives the impression that no other unit could be worthy of such a pilot.
