The KTX-Cheongryong (Korean: KTX-청룡; Hanja: KTX-靑龍), also known as Korail Class 160000 or EMU-320, is a South Korean high-speed electric multiple unit train manufactured by Hyundai Rotem and operated by Korail. It is the second domestically designed and developed high-speed EMU in commercial service (the first being KTX-Eum) in South Korea, which marks the departure of the country's high-speed rail rolling stock from TGV-style power car-unpowered trailer configuration.
