Chan Chan, sometimes itself called Chimor, was the capital city of the Chimor kingdom. It was the largest city of the pre-Columbian era in South America. It is now an archeological site in the department of La Libertad five kilometers (3.1 mi) west of Trujillo, Peru.

Chimor was the political grouping of the Chimú culture. The culture arose about 900 CE, succeeding the Moche culture, and was later conquered by the Inca emperor Topa Inca Yupanqui around 1470, fifty years before the arrival of the Spanish in the region. Chimor was the largest kingdom in the Late Intermediate Period, encompassing 1,000 kilometres (620 mi) of coastline.
