The scrub robins or bush chats are medium-sized insectivorous birds in the genus Cercotrichas. They were formerly in the thrush family, ( Turdidae), but are more often now treated as part of the Old World flycatcher family, ( Muscicapidae). They are not closely related to the Australian scrub-robins, genus Drymodes in the family Petroicidae.

The genus name Cercotrichas is from Ancient Greek kerkos, "tail" and trikhas, "thrush".

Scrub robins are mainly African species of open woodland or scrub, which nest in bushes or on the ground, but the rufous-tailed scrub robin also breeds in southern Europe and east to Pakistan.

The genus contains the following species:

• Karoo scrub robin, Cercotrichas coryphaeus
• Forest scrub robin, Cercotrichas leucosticta
• Bearded scrub robin, Cercotrichas quadrivirgata
• Miombo scrub robin, Cercotrichas barbata
