Tuya Butte is a tuya in the Tuya Range of north-central British Columbia, Canada. It is a bit less isolated from other ranges than neighbouring Mount Josephine. Some of the other volcanoes in the area include South Tuya, Ash Mountain, and Mathews Tuya.

Tuya Butte was the first tuya analyzed in the geological literature, and its name has since become standard worldwide among volcanologists in referring to and writing about tuyas. The Tuya Mountains Provincial Park was recently established to protect this unusual landscape, which lies north of Tuya Lake and south of the Jennings River near the boundary with the Yukon Territory. Tuya Butte is regarded as among the best examples of this landform outside Iceland and Antarctica.

Tuya Butte was named by Canadian volcanologist Bill Mathews in association with adjacent Tuya Lake and Butte Lake. The term tuya may be derived from a Tahltan word.

Tuya Butte is part of the Tuya Volcanic Field, a volcanic field that includes tuyas, postglacial lapilli cones and lava flows and several small shield volcanoes formed during the and Holocene. This in turn is part of the Northern Cordilleran Volcanic Province from Prince Rupert, into the Yukon and the Alaska border caused by rifting of the North American Plate as the Pacific Plate slides northward along the Queen Charlotte Fault.
