Triyuginarayan Temple (Sanskrit: त्रियुगी-नारायण) is a Hindu temple located in the Triyuginarayan village in Rudraprayag district, Uttarakhand, India. The ancient temple is dedicated to god Vishnu. Its fame is credited to the legend of god Shiva’s marriage to goddess Parvati witnessed by Vishnu at this venue and is thus a popular Hindu pilgrimage sites and part of Abhimana Kshethram temples. A special feature of this temple is a perpetual fire, that burns in front of the temple. The flame is believed to burn from the times of the divine marriage. Since ancient times this fire used to be self-igniting but in Kaliyug it is kept burning continuously by the Jamloki Brahmins of Kedarghati. Jamloki brahmins are also the chief worshipper of the Triyuginarayan temple. Thus, the temple is also known as Akhand Dhuni temple.

The temple courtyard is also the source of a water stream, which fills three sacred bathing ponds (kunds) nearby.
