The Amitāyurdhyāna Sūtra (Sanskrit; ) is a Mahayana sutra in Pure Land Buddhism, a branch of Mahāyāna Buddhism. It is one of the three principle Pure Land sutras along with the "Infinite Life Sutra" and the "Amitabha Sutra". Amitāyus is another name for the Buddha Amitābha, the preeminent figure in Pure Land Buddhism, and this sūtra focuses mainly on meditations involving complex visualization.
