The EDM-GA-01 Gundam Lfrith Ur (ガンダム・ルブリス・ウル Gandamu Ruburisu Uru?) is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury and is piloted by Sophie Pulone. Later, this unit is briefly piloted by Elan Ceres.

A Gundam-type mobile suit manufactured by the once-defunct Ochs Earth Corporation with support from the Space Assembly League. It was developed for the purpose of suppressing the Benerit Group and given to the Dawn of Fold, an anti-Spacian organization active on Earth.

It is a substantially upgraded version of the Gundam Lfrith Pre-Production Model produced by Ochs Earth. Though it bears the name of Lfrith, its frame, exterior, and almost everything besides the GUND Format base components are newly manufactured. With new capabilities geared toward short sorties, it boasts superior standard output values than regular battle models. With power surpassing expectations for any mobile suit, the Lfrith Ur is a manifestation of one of the Mobile Suit Development Council's fears concerning GUND-ARM.
