Tham An Mah, (Horse Saddle Cave) is an archaeological site located in the Luang Prabang Province of Laos.

The site was initially excavated in 2010 by a joint team of the Middle Mekong Archaeological Project and the Department of Heritage of Laos.

Finds from trench B included a circular stone disk, possibly made of limestone or a similar material.

Villagers stated that the looters were after the fine sediment inside the cave that could be resold as gardening soil elsewhere.
