The Xi'an Y-20 Kunpeng (Chinese: 运-20 鲲鹏; pinyin: Yùn-20 Kūnpéng; lit. 'Transport-20 Kunpeng') is a large military transport aircraft that was developed by the Xi'an Aircraft Industrial Corporation for the People's Republic of China (PRC).

While the official series name of the aircraft is Kunpeng, a mythical giant fish-bird from the Taoist classic Zhuangzi, it is nicknamed "Chubby Girl" (Chinese: 胖妞; pinyin: Pàng niū) in the Chinese aviation industry because its fuselage is much wider than aircraft previously developed in China.

As of 2013, a single Xi'an Y-20 aircraft cost $160 million. The Y-20 is regarded as a competitor to the Boeing C-17 Globemaster III, which had a unit cost of approximately $340 million as of 2022.
