Hanoi Indoor Games Gymnasium or Mỹ Đình Indoor Athletics Arena (Vietnamese: Cung Điền kinh Hà Nội or Cung Thi đấu Điền kinh trong nhà Mỹ Đình) is an indoor arena in Hanoi, Vietnam. It has a capacity of 3,094 using permanent seating and temporary seating configuration. The arena is a part of Vietnam National Sporting Complex, situated north west of Mỹ Đình National Stadium and Mỹ Đình Aquatics Center.

The venue was one of several projects built to commemorate the Millennial Anniversary of Hanoi. It officially opened on September 19, 2009 after 14 months of construction, in time for the 2009 Asian Indoor Games.

The competition field of the arena has an area of 5,420 m (58,300 sq ft). To prepare for the 3rd Asian Indoor Games, the gymnasium was equipped with a 6-lane 200-meter oval track and a 60-meter straight track, supplied by Mondo. Without the tracks, the field could fit up to 6 tennis courts. The venue was designed to withstand earthquakes up to 5.9 Richter with a life span of 70 years.

After Asian Indoor Games, the tracks were removed and the venue has yet to host another indoor athletics tournament since then. Hanoi Indoor Games Gymnasium has been used mostly for tennis matches, several local sporting events, exhibitions, concerts and other entertainment events.
