Liaoning (help·info) (simplified Chinese: 辽宁; traditional Chinese: 遼寧; pinyin: Liáoníng) is a northeastern province of the People's Republic of China. Its one-character abbreviation is Liao (辽 pinyin: liáo).

"Liáo" is an ancient name for this region, which was adopted by the Liao Dynasty (Khitan Empire) which ruled this area between 907 and 1125. "Níng" means "peacefulness". The modern province was established in 1907 as Fengtian province (奉天 pinyin: Fèngtiān; Postal map spelling: Fengtien) and the name was changed to Liaoning in 1929. Under the Japanese puppet Manchukuo regime, the province reverted to its 1907 name, but the name Liaoning was restored in 1945.

Liaoning is located in the southern part of China's Northeast. Liaoning borders the Yellow Sea (Korea Bay) and the Bohai Gulf in the south, North Korea in the southeast, Jilin Province to the northeast, Hebei Province to the west, and Inner Mongolia to the northwest.

The Yalu River marks the border between North Korea and the Chinese provinces of Jilin and Liaoning. It empties into the Korea Bay between Dandong (Liaoning) and Sinŭiju (North Korea).
