Mara Rosa is a municipality in north-central Goiás state, Brazil.

Mara Rosa is located 356 kilometers north of Goiânia in the Porangatu Microregion.

Highway communications with Goiânia are made by GO-080 / Nerópolis / São Francisco de Goiás / BR-153 / Jaraguá / GO-080 / Goianésia / Barro Alto / GO-342 / BR-153 / Uruaçu / Campinorte / GO-239.

The first houses appeared in 1742, 15 years after the founding of Vila Boa, the former capital of the state.

This settlement was transferred to another site and in 1960 the name was changed to Mara Rosa as a tribute to José Maurício de Moura.

In January 2005 the mayor was Otávio Alves Neto and the vice-mayor was Ostervaldo Gomes de Aguiar.

Most of these people did not move into the town itself but most likely immigrated to the large urban centers of Anápolis, Goiânia, and Brasília.

Mara Rosa is the biggest producer of saffron in the state of Goiás and there are also important plantations of corn, soybeans, and rice.
