The Cuckooshrikes (Campephagidae) family are 92 species of small to medium-sized passerine bird species found in the subtropical and tropical Africa, Asia and Australasia. Cuckooshrikes are closely related neither to the cuckoos nor to the shrikes; the name probably comes from the grey colour of many of the cuckooshrikes. Some of the species also bear a superficial resemblance to cuckoos, and have a similar undulating flight.

The grey colouration has led to one of their other names, the greybird. In some parts of the world they have also been known as caterpillar-birds, a name derived from their diet. Although the majority are predominantly greyish with white and black, the minivets are brightly coloured in red, yellow and black, and the Blue Cuckooshrike of central Africa is all-over glossy blue. The majority are forest birds. Some species are restricted to primary forest, like the New Caledonian Cuckooshrike, others are able to use more disturbed forest. Around eleven species use much more open habitat, one Australian species, the Ground Cuckooshrike being found in open plains and scrubland with few trees.
