Cachoeira João Fernandes is a waterfall located in the Bocaina region of the Parque Nacional da Serra do Cipó, in Minas Gerais. It forms on the Ribeirão do Gavião — also referred to as Córrego do Gavião — which is a tributary of the Córrego Palmital.

The falls sit on an upper plateau within the Serra da Bandeirinha. The waterfall lies close to its neighbor, Cachoeira do Palmital, and the two are considered part of the same family of watercourses.

Nearby, the Gavião also features other points of interest, including the Poço da Areia.

The broader Bocaina valley is home to several other well-known falls, such as the Gavião, Andorinhas, and Tombador waterfalls, all situated in the lower reaches of the valley.

The confluence of the Palmital and Gavião streams is marked by the historic Retiro Velho site.
