Rondon's marmoset (Mico rondoni), also known as the Rondônia marmoset, is a small species of monkey from the family Callitrichidae found in the south-western Amazon in Brazil. It is endemic to the state of Rondônia, and its range bordered by the Rio Mamoré, Rio Madeira, Rio Ji-Paraná, Serra dos Pacaás Novos and possibly Bolivia. It was only described in 2010, and its name refers to the famous Amazonian explorer Cândido Rondon. Prior to its description, it was included in Emilia's marmoset (Mico emiliae).

It has dark fur on much of its head, forehead and the sides of its face, which contrasts with a whitish patch in the middle of its forehead. The fur on its legs become reddish-brown on its shins and almost black at the ankles. Its tail is mostly black. It averages about 330 grams (12 oz) in weight.
