Rhegmatorhina is a genus of birds within the family Thamnophilidae, belonging to the order Passeriformes. Rhegmatorhina is one of the six genera in the Thamnophilidae family, whose birds follow army ants and capture arthropods fleeing their attacks, often described as dedicated or professional ant followers.

The genus contains the bare-eyed antbird (Rhegmatorhina gymnops), chestnut-crested antbird (Rhegmatorhina cristata), Harlequin antbird (Rhegmatorhina berlepschi), hairy-crested antbird (Rhegmatorhina melanosticta) and white-breasted antbird (Rhegmatorhina hoffmannsi).

The genus Rhegmatorhina was proposed by American ornithologist Robert Ridgway in 1888 and was officially described and named by Ridgway in his book Descriptions of New Species and Generations of Birds from the Lower Amazon in the same year. The name Rhegmatorhina originates from Greek, where "rhegma" (ῥῆγμα) means "cleft", and "rhina" (ῥῖνᾰ) means "nostril", which together means "having cleft like nostrils", depending on the external characteristics of the bird species within the genus.
