Dorjidak Gompa (Tibetan: རྡོ་རྗེ་བྲག་དགོན་པ།, Wylie: rdo rje brag dgon pa "Indestructible Rock Vihara") or Tupten Dorjidak Dorjé Drak Éwam Chokgar (Tibetan: ཐུབ་བསྟན་རྡོ་རྗེ་བྲག་རྡོ་རྗེ་བྲག་ཨེ་ཝཾ་ལྕོག་སྒར་, Wylie: thub bstan rdo rje brag rdo rje brag e waM lcog sgar) is a Tibetan Buddhist monastery and one of the Nyingma school's "Six Mother Monasteries" in Tibet. It is located in the Lhoka (Shannan) Prefecture in the south of the Tibet Autonomous Region, older southeastern Ü-Tsang.

Dorje Drak is also the name of the monastery built to replace it in Shimla, India after the original was destroyed during the Battle of Chamdo. It is now the seat of the throne-holder of the monastery and the tradition. Along with Mindrolling Monastery it is one of the two most important Nyingma monasteries in the region of Ü.

The earlier name of Dorje Drak was Ewam Chogar Gompa, built by Ngari Panchen Pema Wangyal (1487-1582). It was enlarged by Pema Wangyal's tulku Jangdag Tashi Tobgyal Wangpode (1550-1602). Jangdag Wangpode’s son was the first Rigdzin Ngaggi Wangpo and also the third lineage holder. The two earlier incarnations and lineage holders were entitled Rigdzin in honor of the reestablishment of the monastery in 1630-1632 by Ngaggi Wangpo.

At the monastery's relocation site, a footprint of Padmasambhava (Pad-ma ‘byung-gnas), also known as Guru Rinpoche, was found on the rock mountain behind the monastery, along with a naturally formed crossed vajra. Considered auspicious, it led to the addition of "Indestructible Rock" to the monastery's founding name: Ewan Chogar Gompa became Thubten Dorje Drag Ewam Chogar, known of as Dorje Drak. Another Sister Monastery, Katok Monastery also was located on a naturally occurring crossed vajra.

In 1632 the monastery relocated from Tsang to its present tranquil setting on the north bank of the Brahmaputra, when the young Third Rigdzin Ngagiwangpo and his guardian Jangdak Tashi Topgyel were forced to flee the wrath of the kings of Tsang. Their successor, the erudite Fourth Rigdzin Pema Trinle (b. 1641) greatly enlarged the monastery before his untimely death at the hands of the Dzungar Mongolians, who sacked the monastery in 1717.

Rebuilding began in 1720, under patronage of the 7th Dalai Lama, Kelzang Gyatso. However, when Kelzang Pema Wangchuk, The Fifth Dorje Drak Rigdzin (1719/20-1770/71) was enthroned as the monastery's third throne holder, its buildings were still lying mostly in ruins.

The Sixth Dorje Drak Rigdzin, Kunzang Gyurme Lhundrub (d. 1808?) is remembered for "building and maintaining the monastery." He "gave teachings, commissioned numerous objects of faith, sponsored the printing of scriptures, and emphasized the study of the Jangter and other traditions' texts."

Later, during the 1960s the monastery was again obliterated. Nonetheless it has been gradually restored in recent years through the efforts of the present incarnation of Dordrak Rigdzin, who lives in Lhasa, and those of Kelzang Chojor and the local community.
