MiMi Aung (Burmese: မိမိအောင်, Burmese pronunciation: [mḭ mḭ àʊɰ̃]; born 1968) is a Burmese-American engineer. Currently, she is director of technical program management for Amazon's Project Kuiper, an initiative to increase broadband internet access through an array of satellites in low Earth orbit.

Aung was born in the United States, where her parents met, though her family returned to Burma when she was 2 years old. After spending her childhood in Burma and Malaysia, Aung returned to the United States at age 16 and studied engineering at the University of Illinois at Urbana-Champaign, where she received her Bachelor's and master's degrees.

In 1990, she joined NASA's Jet Propulsion Laboratory (JPL). She was a lead engineer on the Mars Helicopter Ingenuity, the first extraterrestrial aircraft. On February 18, 2021, Ingenuity arrived on Mars, and on April 19 it took its first 39-second flight. Aung said, it “was an incredible moment” and “This morning our dream came true.” The flight was being compared to the first flight in 1903 of the Wright brothers' airplane, a small piece of which was carried by the helicopter to Mars.
