The buff-breasted wren (Cantorchilus leucotis) is a species of bird in the family Troglodytidae. It is found in the Amazon Basin of northern Brazil and Amazonian Colombia, Ecuador, Peru and northern-border Bolivia, and also the Guianan countries of Guyana, Suriname, and French Guiana.

Male buff-breasted wrens weigh 18.5 to 22.8 g (0.65 to 0.80 oz) and females are lighter at 16.0 to 19.5 g (0.56 to 0.69 oz), but the sexes are otherwise similar. There is considerable variation in plumage across the species' wide range. Adults' head, nape, shoulders, tail, and back are rufescent to grayish brown; the tail is heavily barred.
