It is the fourth most populous municipality in the state, following Natal, Mossoró, and Parnamirim, with a population of 124,495 inhabitants in 2025.
The municipality is known for being the site of one of the most significant events in the history of Rio Grande do Norte and Brazilian Catholicism, when Dutch forces massacred eighty individuals in an event known as the Uruaçu Massacre, which occurred in 1645. In 2017, these martyrs were canonized as saints in Saint Peter's Square, in a ceremony presided over by Pope Francis.

Since 2014, it has been home to the Governador Aluízio Alves International Airport, a Brazilian airport complex, which was the first Brazilian airport to be privatized and serves the cargo and passenger transport demands of the Natal Metropolitan Region.
History
The territory that now constitutes São Gonçalo do Amarante was originally inhabited by the Potiguara Indians, among whom Poti, known as Filipe Camarão, stood out, originating from a community in Extremoz.
The municipality's name derives from Gundisalvus of Amarante, a Portuguese ecclesiastic and the patron saint of the city of Amarante in Portugal. São Gonçalo do Amarante saw its first settlers in the 17th century, with the family of Estevão Machado de Miranda, who were soon massacred by the Dutch in the massacre of Cunhaú and Uruaçu in 1645. It was not until 1689 that expeditions from Pernambuco led to the repopulation of the area after the expulsion of the invaders.
In the 18th century, in 1710, near the Potengi Mill, Paschoal Gomes de Lima and Ambrósio Miguel Sirinhaém, both Portuguese natives, settled with their families along the banks of the eponymous river. After settling, they built their residences and constructed a small church dedicated to the saint Gundisalvus of Amarante. The municipality's name comes from the stone statue of the saint that was placed on the altar.
On 11 April 1833, during the administration of Manoel Lobo de Miranda Henrique, the municipality of São Gonçalo do Amarante was established. In 1856, under the governance of Antônio Bernardes de Passos, the municipality was struck by a cholera epidemic that claimed 171 lives. In 1868, through a provincial law sanctioned by Governor Gustavo Augusto de Sá, the municipality lost its autonomy and was annexed to the municipality of Natal, the provincial capital. Six years later, the village was detached and restored to municipal status.
However, in 1879, the population of São Gonçalo do Amarante suffered a setback when the municipal government seat was transferred to the village of Macaíba, previously known as Cuité. In 1890, shortly after the proclamation of the republic, José Inácio Fernandes Barros, the vice-president of Rio Grande do Norte, elevated the village of São Gonçalo do Amarante, then part of Macaíba, to municipal status.
With State Decree-Law No. 268 of 1943, São Gonçalo do Amarante once again lost its political autonomy, reverting to a district of Macaíba under the name Felipe Camarão, and losing part of its territory, which formed the current municipality of São Paulo do Potengi. It was only with the enactment of State Law No. 2324 on 11 December 1958, that the district definitively gained political emancipation, and its name was changed from Felipe Camarão back to São Gonçalo do Amarante.
