Suktagendor is an archaeological site of the Indus Valley Civilization located on the Iran border in the current Balochistan province of Pakistan.

- Sutkagendor was discovered in 1875 by Major Edward Mockler, who conducted small-scale excavation.

In 1928 Aurel Stein visited the area as part of his Gedrosia tour and carried out further digs.
- In October 1960, Sutkagendor was more extensively excavated by George F. Dales as a part of his Makran Survey, uncovering structures made from stone and mud bricks without straw.
