Kongar-ol Ondar (Tuvan: Ондар Коңгар-оол, March 29, 1962 – July 25, 2013) was a master Tuvan throat singer and a member of the Great Khural of Tuva. Ondar was born near the Khemchik River in western Tuva. Considered a living treasure by the Republic of Tuva, Ondar was granted a stipend and an apartment for the musical skills he possessed. Jovial and personable, Ondar is probably the best-known face of khöömei (Tuvan: хөөмей) throat singing to Westerners, appearing on the Late Show with David Letterman and in interviews for CNN and other networks.

In the Central Asian tradition of self-fulfilling child naming, Kongar-ol literally translates to "loud boy."
