The striated antbird (Drymophila devillei) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.

The striated antbird is 13 to 14 cm (5.1 to 5.5 in) long and weighs 10 to 12 g (0.35 to 0.42 oz). Adult males of the nominate subspecies have a black crown and back with thin white streaks and a large white patch between the scapulars. Their rump is orangish buff. Their flight feathers are slate gray with cinnamon edges and their wing coverts black with white tips. Their tail is black with wide white tips to the feathers and large white spots on the innermost pair. Their face, throat, and underparts are white with bold black streaks on the face, sides of the neck, and breast. Females have the same pattern but different colors than males. Their upperparts have buff rather than white streaks; their underparts are pale buff with thin black streaks on the breast. Juveniles have olive-gray upperparts and buff-tinged underparts with an olive-gray band on the breast. Subadult males resemble adult females. Both sexes of subspecies D. d. subochracea have ochraceous buff underparts that are darker on the breast and flanks. Females have darker ochraceous streaks on their upperparts than the nominate. Adults of both sexes of both subspecies have a brown iris, a black maxilla, a gray to blue-gray mandible, and blue-gray legs and feet.
