Liaoning is a northeastern province of the People's Republic of China. 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).

Liaoning is located in the southern part of China's Northeast. The Qin and Han dynasties were able to establish rule over much of what is Liaoning; later on governments headed by various people such as the Xianbei, Goguryeo, Khitan and Jurchen ruled Liaoning. In the seventeenth century, the Manchus established their capital in modern Shenyang, Liaoning, before they conquered the rest of China and set up the Qing Dynasty in 1644. In the last half of the seventeenth century the imperial government recruited migrants from Shandong to settle the relatively sparsely populated area. Many of the current residents of Liaoning trace their ancestry to these seventeenth century settlers. For the rest of the Manchu era, China's Northeast was off-limits to Han Chinese, and was ruled by three generals, one of whom, the General of Shengjing, ruled much of modern Liaoning.

In paleontology, Liaoning is well known for its extraordinary fossils from the Lower Cretaceous period; e.g., the early 'placental' mammal known as Eomaia. The first widely acknowledged feathered dinosaur, Sinosauropteryx prima, was discovered in Liaoning and unveiled at a scientific meeting in 1996. Other notable discoveries have been an intact embryo of a pterosaur, Repenomamus robustus—a cat-sized mammal who ate dinosaurs, and Sinornithosaurus millenii, nicknamed "Dave the Fuzzy Raptor".

The Mukden Palace was the palace of the Qing Dynasty emperors before they conquered the rest of China and moved their capital to Beijing. Though not as large nor as famous as its counterpart (the Forbidden City) in Beijing, the Mukden palace is significant for its representation of palace architecture at the time, and has recently been included on the UNESCO World Heritage Site as an extension of the Imperial Palace site in Beijing.

In addition, three imperial tombs dating from the Qing Dynasty are located in Liaoning. These tomb sites have been grouped with other Ming and Qing Dynasties tombs (such as the Ming Dynasty Tombs in Beijing, and the Ming Xiaoling Mausoleum in Nanjing) as a combined UNESCO World Heritage Site.

Wunu Mountain City, a Goguryeo site found in Huanren Manchu Autonomous County, is part of a combined UNESCO World Heritage Site that also includes sites in Ji'an, Jilin.
