Marpa Lotsawa (1012–1097), sometimes known fully as Lhodak Marpa Choski Lodos or commonly as Marpa the Translator, was a Tibetan Buddhist teacher credited with the transmission of many Buddhist teachings to Tibet from India, including the teachings and lineages of Vajrayana and Mahamudra.

Born as Marpa Chökyi Lodrö, in Lhodrak Chukhyer in the southern part of Tibet, to an affluent family, he began studying at a young age but was wild and untamed compared to other children. Marpa first received instruction for three years at Mangkhar with Drokmi Shakya Yeshe and mastered Sanskrit. He decided to travel to India to study with renowned Indian Buddhist masters. Marpa returned home to Lhodrak and converted his entire inheritance into gold to fund his travel expenses and to make offerings to teachers.

Marpa journeyed first to Nepal where he studied with Paindapa and Chitherpa, two famous students of Naropa. Paindapa later accompanied Marpa to Pullahari, near Nalanda University, where Naropa taught. Marpa spent twelve years studying with Naropa and other great Indian gurus, most prominently Maitripada. After twelve years he set forth on his journey back to Tibet to teach and continue his dharma activities.
