Yinxu is a Chinese archeological site corresponding to Yin, the final capital of the Shang dynasty. Located in present-day Anyang, Henan, Yin served as the capital during the Late Shang period which spanned the reigns of 12 Shang kings and saw the emergence of oracle bone script, the earliest known Chinese writing. The site's existence had been forgotten for millennia, along with that of oracle bone script and other material evidence of the Shang's existence. It was only rediscovered in 1899, following an investigation into oracle bones that were found being sold near the site. The rediscovery of Yinxu marked the beginning of decades of its intensive excavation and study. It is one of China's oldest and largest archeological sites, and was selected as a UNESCO World Heritage Site in 2006. Yinxu is located in northernmost Henan province near the modern city of Anyang, and near the Hebei and Shanxi province borders. Public access to the site is permitted.

The Shang dynasty, also known as the Yin dynasty, was a Chinese royal dynasty that ruled in the Yellow River valley during the second millennium BC, traditionally succeeding the Xia dynasty and followed by the Western Zhou dynasty. The classic account of the Shang comes from texts such as the Book of Documents, Bamboo Annals and Records of the Grand Historian. Modern scholarship dates the dynasty between the 16th and 11th centuries BC, with more agreement surrounding the end date than beginning date.
