Khusein-bek Mausoleum, Mausoleum ruins in Chishminsky District, Bashkortostan, Russia.

Khusein-bek Mausoleum is a square stone tomb measuring 8.5 by 8.5 metres, with walls 1.1 metres thick and a dome rising 5.28 metres. Its south entrance is 1.07 metres wide and 2.45 metres high, and arched window openings pierce the other walls. Inside, nine graves were found, the central one enclosed by an oval stone fence.

Hadji-Husayn-bek, a Sufi of the Yasawiyya brotherhood from Turkestan, died in 1341–42 (10 Muharram 744 AH) and was buried on a hill of the Akzirat cemetery. The present mausoleum was built in the first half of the 14th century; by the 18th century it was ruined, and in 1911 Ufa mufti Mukhamedyar Sultanov ordered its restoration. In 2016 Husayn-bek's remains, kept since the 1985 excavations, were reburied inside.

Every year Chishminsky District holds memorial events for Khusein-bek, and in 2014 a cathedral mosque in the village of Chishmy was named after him. The burial ground around the mausoleum, Akzirat, keeps old gravestones; the 1911 excavations found nine burials, six of them children. His gravestone, now kept in a museum, gives his death as 10 Muharram 744 AH at the age of 76.

The site sits in a rural setting and can be reached on foot, though you should be prepared for uneven paths and open terrain. It is wise to check ahead about access conditions, as restoration work or protective measures may sometimes limit when you can visit.

The mausoleum stands on Akzirat cemetery, whose name means "white cemetery". Its central grave is enclosed by an oval stone fence, and the tombstone bearing the epitaph is now kept in a museum rather than at the grave. The Arabic inscription gives the date 10 Muharram 744 AH and the age of 76.
