Emarginata is a genus of birds in the Old World flycatcher family Muscicapidae that occur in southern Africa.

The three species in the genus were previously placed in the genus Cercomela. A molecular phylogenetic study published in 2010 found that Cercomela was polyphyletic and that the type species Cercomela melanura (the blackstart) lay in a clade containing members of Oenanthe.{{cite journal | last1=Outlaw | first1=R.K. | last2=Voelker | first2=G. | last3=Bowie | first3=R.C.K. | year=2010 | title=Shall we chat?

The three species in the genus are:

• Karoo chat (Emarginata schlegelii)
• Tractrac chat (Emarginata tractrac)
