[6] The history of Serra Negra do Norte begins at the time of Colonial Brazil, when a large lot was donated to Francisco de Oliveira Toledo.

The construction of this chapel was the starting point for the accelerated population growth in Serra Negra on the banks of the Espinharas River.

Five years later, the village of Serra Negra was elevated to the category of city, being, at the same time, created in the district of São João do Sabugi.

Thus, the municipality started to be formed by the districts of Serra Negra do Norte and São João do Sabugi.

In 1948, the district of São João do Sabugi is emancipated from Serra Negra do Norte and becomes a new municipality in Potiguar.
