Yogambara (Tibetan: nam khai nal jor), is a tutelary deity in Tibetan Buddhism belonging to the Wisdom-mother class of the Anuttarayoga tantra.
It was made famous in the Vajravali text of the Indian Pandita Abhayakaragupta and through the tradition of Marpa and Ngog lotsawa.
Semi-wrathful in appearance, he is dark blue in colour, and has three faces, blue, white and red.
