Moe Thu Aung (born 10 June 1981) is a Burmese former swimmer, who specialized in sprint freestyle and butterfly events.

[1] Aung represented Myanmar at the 2000 Summer Olympics, received a total of ten medals (one gold, six silver, and three bronze) from all editions of the Southeast Asian Games since 2001, and later became a top 8 finalist in a sprint freestyle double at the 2002 Asian Games.

[4] She participated in heat one against two other swimmers, 12-year-old Fatema Hameed Gerashi of Bahrain and Paula Barila Bolopa of Equatorial Guinea.

Aung pulled away from a small field to an unexpected triumph in a new Burmese record of 26.80, finishing farther ahead of Gerashi, who was later disqualified from the race for a no false-start rule attempt, and Bolopa, who posted the event's slowest time in Olympic history (1:03.97).

[7][8] At the 2001 Southeast Asian Games in Kuala Lumpur, Malaysia, Aung edged out Singapore's top favorite Joscelin Yeo by seven hundredths of a second (0.07) to capture the 50 m freestyle title in 26.34, adding it to two other silver medals from her hardware in the 100 m freestyle (57.61) and in the 100 m butterfly (1:01.76).
