Suj Tilla or Suitilla[1] is a Himalayan peak located on the eastern side of Uttarakhand state in Pithoragarh District of India.

The peak is located above the junction of Kalabaland, Sankalp and Yankchar glaciers.

This peak was first climbed in 2001 by an Indo-British joint expedition by two Britishers Graham Little and Jim Lowther.

The climbers who made the summit are Divyesh Muni, Lt. Amit Pande, Sherpa Nima Dorje, Lt. K S Balaji, Lt. Amit Rajora, Chera Rajkumar, A. Chaudhury, Sherpa Tsange, Puri and Nima Thondup.

This peak is still unclimbed due to multiple cornices on the ridge.
