Anshan (Chinese: 鞍山; pinyin: Ānshān; literally: "saddle mountain") is an inland prefecture-level city in central-southeast Liaoning province, People's Republic of China. It is located about 92 kilometres (57 miles) south of the provincial capital of Shenyang. As of the 2020 census, it was Liaoning's third most populous city with a population of 3,325,372 people. It has an area of about 9,270 km2 (3,580 sq mi) spanning 133 km (83 mi) from east to the west.

The city's name came from the horse saddle-like shape of a nearby mountain south of the city. Anshan is home to the Anshan Iron and Steel Group, one of the largest steel makers in China. Anshan holds one-third of the world's supply of talcum and a quarter of the world's reserves of magnesite. Anshan also produced the largest ever jade stone, now a local tourist attraction carved as a Buddha statue.
