Mammoth Yosemite Airport is a town-owned public airport east of Mammoth Lakes, in Mono County, California, United States. Also known as Mammoth Lakes Airport or Mammoth–June Lake Airport, it is mainly used for general aviation, but has scheduled passenger flights operated by one airline which primarily serves the airport on a seasonal basis during the winter ski season. Additional scheduled passenger service for the Mammoth area is seasonally available at the nearby Eastern Sierra Regional Airport located in Bishop, CA.

Historical airline service United Airlines served the airport beginning in December 2010, via United Express. Initially service was only provided during winter months. In 2010 this became a year-round service. In December 2021, all of the United Express service moved to nearby Eastern Sierra Regional Airport in Bishop, California, as the airline made a decision that MMH could no longer support scheduled commercial flights because of poor operational reliability primarily due to weather issues.
