Trikut Pahar (also: Trikut Parvat, Hindi त्रिकुट पर्वत, English Trikut Hills, German Trikut Mountains) is a mountain massif and Hindu pilgrimage site near the town of Deoghar in the Deoghar district in the Indian state of Jharkhand.
The town of Deoghar is about 15 kilometers away to the west. Between Deoghar and Trikut Pahar lies Tapovan, about 10 kilometers west of Trikut Pahar, which is known for the Taponath Mahadev temple and a temple of Hanuman. The NH 133 road runs past the massif in the north, and the NH 114A road in the south.
The Mayurakshi River originates from the Trikut Pahar and flows through Jharkhand and the districts of Birbhum and Murshidabad in West Bengal before joining the Hooghly River.
