Ucchuṣma (Chinese: 穢跡金剛; Pinyin: Huìjì Jīngāng; Rōmaji: Ususama Myōō) is a Vidyārāja in Mahayana and Vajrayana Buddhism. Ucchuṣma's full name in Sanskrit sources is Vajra Krodha Mahābala Ucchuṣma (lit. "Great Strength Furious Diamond Ucchuṣma"). In Chinese, this is translated as 大力威怒金刚烏芻使摩 (pinyin: Dàlì Wēinù Jīngāng Wūchúshǐmó), from the Chinese version of the Sūtra of Mahābala and the Tibetan version of the Ārya-Mahābalanāma Mahāyāna Sūtra.
