Trailokya Malla was a Malla dynasty king of Bhaktapur, Nepal from 1560 to 1613. Ganga Rani, the mother of Trailokya, made both her sons Tribhuvana and Trailokya the co-kings of Bhaktapur. Ganga Rani was first a regent for her two sons, but later became the co-ruler or ruling queen of Bhaktapur. It is believed that Trailokya was murdered one night while taking his dinner, which had been spiked with poison.
