Red-backed Shrikes are not much larger than sparrows, but they have distinctive strong beaks and long tails. Males have reddish brown colouring on their back and wings, and a bluish grey cap and nape, with a black mask-like eye-stripe. Their underparts are pale with a pinkish tinge on the chest. Their tails are black with white patches on the base of their outermost tail feathers. Females have rusty brown upper parts and paler underparts with crosswise streaked patterning. They also have less distinct dark brown masks. Juveniles resemble females but have more reddish brown backs and more prominent streaked patterning also on their upper parts.

Red-backed Shrike’s legs are blackish (male) or brownish grey (female). Their beaks are black (male) or dark brown (female). They have dark brown irises.
