The Delta Amacuro softtail (Thripophaga amacurensis) is a Vulnerable species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to the southern Orinoco Delta in northeastern Venezuela.

The Delta Amacuro softtail is about 17 cm (6.7 in) long and weighs 26 to 30 g (0.92 to 1.1 oz). The sexes have almost the same plumage. Adult males have olive-buff lores with dark gray tips and a grayish olive eyering; the rest of their head is brownish olive with yellow-buff spots. Their upper back is brownish olive with yellow-buff streaks. Their rest of their back is plain warm brown and their rump and uppertail coverts rufous-brown or cinnamon. Their tail is cinnamon that is brighter on its upper side. Their upperwing coverts are warm olive-brown to fulvous-brown. Their primaries and secondaries are dusky with warmer brown edges on the outer webs and their tertials are rufescent brown. Their chin is cinnamon-buff, their throat rufous chestnut, and their breast and belly brownish olive with buffy teardrops that become less well defined on the latter. Their flanks and thighs are plain brownish olive and their undertail coverts tinged warm ochraceous tawny. Their iris is rusty brown, their bill steel gray with dusky at the maxilla's base and pale pink at the mandible's, and their legs and feet dull yellowish green. Females differ only in having a paler chin and throat than males.
