The locality was called Fazenda do Leonardo and occupied the region where the urban agglomeration of Maquiné is located today.

European immigrants basically dedicated themselves to subsistence agriculture, growing maize, wheat, beans and rice.

At that time, Fazenda and the district of Marquês do Herval (currently Barra do Ouro) belonged to and were administered by the municipality of Osório.

In the district of Morro Alto, a quilombola community was formed that resist and persists in the place until the present day.

When his "engine" broke down, Mr. João Vidor installed a powerful boiler that operated a mill, a peeler and a sawmill during the day and generated electricity at night.

In 1938 the locality was called "Vila General Daltro Filho", a name that generated political tensions, so that two years later it was renamed "Maquiné", a name that it maintains until today.

In 1947 there was a major navigation accident, resulting in the death of 18 people, including deputy Osvaldo Bastos.
