Samantabhadra (Sanskrit; 'Universal Worthy') is a bodhisattva in Mahayana Buddhism associated with practice and meditation. Together with Gautama Buddha and his fellow bodhisattva Manjusri; he forms the Shakyamuni trinity in Buddhism. He is the patron of the Lotus Sutra and; according to the Avatamsaka Sutra; made the ten great vows which are the basis of a bodhisattva.

In Japan; this bodhisattva is often venerated by the Tendai and in Shingon Buddhism; and as the protector of the Lotus Sutra by Nichiren Buddhism. In the Nyingma school of Tibetan Buddhism; Samantabhadra is also the name of the Adi-Buddha - in indivisible Yab-Yum with his consort; Samantabhadri.
