The Neo-Inca State, also known as the Neo-Inca state of Vilcabamba, was the Inca state established in 1537 at Vilcabamba by Manco Inca Yupanqui. It is considered a rump state of the Inca Empire (1438–1533), which collapsed after the Spanish conquest in the mid-1530s. The Neo-Inca State lasted until 1572, when the last Inca stronghold was conquered, and the last ruler, Túpac Amaru, was captured and executed, thus ending the political authority of the Inca state.

Vilcabamba or Willkapampa is often called the Lost City of the Incas. Vilcabamba means "sacred plain" in Quechua. The modern name for the Inca ruins of Vilcabamba is Espíritu Pampa. Vilcabamba is located in Echarate District of La Convención Province in the Cuzco Region of Peru.
