The blue cuckooshrike (Cyanograucalus azureus) is a species of bird in the Cuckooshrike family, Campephagidae. It is widespread across the African tropical rainforest, from Sierra Leone and Liberia to eastern and south-western Democratic Republic of Congo. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests. This species was formerly placed in the genus Coracina. A molecular phylogenetic study published in 2010 found the genus Coracina was non-monophyletic. In the resulting reorganization to create monophyletic genera, the blue cuckooshrike is the only species placed in the resurrected genus Cyanograucalus.
