Trisul is a group of three Himalayan mountain peaks of western Kumaun, Uttarakhand, with the highest reaching 7120m. The three peaks resemble a trident - in Sanskrit, Trishula, trident, is the weapon of Shiva. The Trishul group forms the southwest corner of the ring of peaks enclosing the Nanda Devi Sanctuary, about 15 kilometres (9 mi) west-southwest of Nanda Devi itself. The main peak, Trisul I, was the first peak over 7,000 m (22,970 ft) to have ever been climbed, in 1907.

The trishula is a trident, a divine symbol, commonly used as one of the principal symbols in Hinduism. It is most commonly associated with the deity Shiva and widely employed in his iconography.
