Nathlaung Kyaung is a Hindu temple in Bagan dedicated to the god Vishnu, and is by some historians believed to be the oldest temple in Bagan, built in 931 AD and thus preceding the arrival of Theravada Buddhism in Pagan (fig.) by more than a century.

The temple originally contained free-standing images of Vishnu, as well as bas-relief of this deity on each of the four sides, while the outside walls once contained statues of the 10 avatars of Vishnu, including of the Sakyamuni Buddha, though only seven remain today.
