Empresa de Transportes Aéreos Norte do Brasil Ltda – Aeronorte was a Brazilian airline founded in 1940 that operated in the north and northeast regions of Brazil. It was bought by Aerovias Brasil in 1953 but maintained some degree of autonomy. When Varig bought Aerovias Brasil, Aeronorte was incorporated into Varig.

Aeronorte was founded on December 30, 1949. In December 1950 Aeronorte rented a Junkers Ju 52 from VASP, and initiated flights from São Luís to Belém, to Carolina, and to Fortaleza, Recife and Salvador da Bahia.^[1][2]

It was acquired by Aerovias Brasil on January 15, 1953, but continued to operate as an autonomous unit in partnership with its new owner.^[3] When Real Transportes Aéreos acquired Aerovias Brasil in 1954 Aeronorte continued to operate with some autonomy as part of the consortium. This arrangement was dissolved in 1961 when Varig bought and integrated Aerovias Brasil, Real and its subsidiaries.^[4]

In January 1956 Aeronorte served 24 cities in the northeast region of Brazil.^[5]
