Dugand's antwren (Herpsilochmus dugandi) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds".

Adult females have a rufous crown and nape and buffy underparts (darker on the breast); they are otherwise like males.

It is found from extreme southern and southeastern Colombia south through eastern Ecuador and into northeastern Peru north of the rios Marañón and Amazon.

It typically feeds between 20 and 40 m (65 and 130 ft) above the ground at the ends of leafy branches and in the crown of trees.

It forages actively and usually captures prey by gleaning leaves, stems, and vines by reaching from a perch.

It was a cup of green moss with some lichens in a branch fork 35 m (115 ft) above the ground and well hidden in leaves.

The song of Dugand's antwren is "a fairly rapid, accelerating series of rich notes...tchew-chew-tew-tew 'tu 'tu 'tu 'tututututu" and its call "a quiet tchew".
