The white-crowned tapaculo (Scytalopus atratus) is a species of bird in the family Rhinocryptidae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela.

The white-crowned tapaculo is 12 cm (4.7 in) long. Males weigh 24.6 to 32.5 g (0.87 to 1.15 oz) and one female weighed 25.3 g (0.89 oz). The male of the nominate subspecies is mostly blackish above and slightly lighter below. The flanks and vent are reddish brown and have black bars. It has a white patch on the crown of the head. The female is paler than the male and washed with brown above and is more reddish on the flanks. The juvenile is rust colored with heavy barring. The male S. a. nigricans is darker than the nominate and the female is gray underneath. The male S. a. confusus is paler than the nominate (slaty black) with a brownish lower back. The reddish brown on the flanks and vent, however, covers more area and has heavier barring.
