The Shenyang WS-15 (Chinese: 涡扇-15; pinyin: Wōshàn-15), codename Emei, is a Chinese afterburning turbofan engine designed by the Shenyang Aeroengine Research Institute and manufactured by the Shenyang Liming Aircraft Engine Company.

The WS-15 is intended to become the main engine of the Chengdu J-20 stealth aircraft, enabling it to supercruise, improve its range, manoeuvrability and upgrade potential for future weapon systems. It will eventually replace the Shenyang WS-10, which currently serves as the interim engine of J-20, while the WS-15 is being refined.
