Diskit Monastery also known as Deskit Gompa or Diskit Gompa is the oldest and largest Buddhist monastery (gompa) in the Nubra Valley of Ladakh, northern India.

It belongs to the Gelugpa (Yellow Hat) sect of Tibetan Buddhism. It was founded by Changzem Tserab Zangpo, a disciple of Tsong Khapa, founder of Gelugpa, in the 14th century. It is a sub-gompa of the Thikse gompa.

Lachung Temple and Hundur Monastery are also located nearby, the latter is below the main road near a bridge.

The monastery has statue of Cho Rinpoche (Crowned Buddha) in the prayer hall, a huge drum and several images of fierce guardian deities. An elevated cupola of the moanstery depicts a fresco of the Tashilhunpo Monastery of Tibet.

The Monastery administration runs a school, with support from a Non-Government Organization (NGO) known as the "Tibet Support Group", which has computer facilities and teaches science subjects, in English, to Tibetan children of the region.

A popular festival known as Dosmoche or the "Festival of the Scapegoat" is held in the precincts of the monastery in February during the winter season, which is largely attended by people from villages of the Nubra Valley since the other regions in Leh are inaccessible during this period due to heavy snow fall.
