Ngoyo was a kingdom of the Woyo ethnic group, located in the south of Cabinda and on the Atlantic coast of Central Africa, just north of the Congo River.

[2]: 24–25  Ngoyo tradition held that the kingdom's ancestors were among the earliest settlers in the area, leading their chiefs to title themselves the nfumu nsi ("lords of the earth").

When Antonio II Baretto da Silva invaded, the English forces tried to stop him and protect the interests of Ngoyo, but they were unsuccessful and Baretto da Silva imposed for peace terms.

[5] In 1783, Ngoyo joined forces with the neighboring state of Kakongo to destroy a Portuguese fort.

However, the kingdom was soon undone by the growing financial burden that the kingship entailed.
