Juan Bravo (c. 1483, Atienza–24 April 1521, Villalar de los Comuneros) was a leader of the rebel Comuneros in the Castilian War of the Communities.
His father was Gonzalo Ortega Bravo de Laguna, and his mother was María de Mendoza, daughter of the Count of Monteagudo. In 1504 he married Catalina del Río, they went to live in Segovia, and they had a daughter called María de Mendoza.
In 1510 he married a second time, to María Coronel, grand daughter of Abraham Seneor, a converso. They had two sons, Andrea Bravo de Mendoza and Juan Bravo de Mendoza.
He took part in the Castilian War of the Communities, and he was a leader of the rebel army which was defeated at the Battle of Villalar. He was captured, and beheaded the day after the battle together with Juan Lopez de Padilla and Francisco Maldonado.
There is now a monument to him in Segovia.
Juan Bravo allegedly asked to die first, so as not
to witness the death of so good a knight as Padilla.
