D. Jerónimo de Ataíde, 6th Count of Atouguia (1610 – 16 August 1665) was a Portuguese nobleman and colonial administrator, Governor-General of Brazil from 1654 to 1657.

He repressed acts of rebellion by the Indians (Nobreza de Portugal, volume II, page 335) and exercised a model administration full of honesty and balance, unfortunately almost limited to the captaincy of Bahia, because, from the death of Mem de Sá, the governors of the other captaincies were arrogating successive prerogatives, only theoretically recognizing the hegemony of the Governor-General.

D. Leonor de Meneses was heiress, among other ties, of the former morgado of Carvalho, which would thus pass to the house of Atouguia, remaining there until the execution of the 11th count in 1759, in the so-called Távoras process.

Leonor published, under the pseudonym Laura Múrcia, the work El Desdichado mas firma (Lisbon, 1655).

[4] Passionate about genealogy, he wrote «Nobiliario das Familias d'este Reyno», four volumes, a manuscript that was preserved in the bookstore of the convent of Graça, in Lisbon.
