Cyanistes
Cyanistes is a genus of birds in the tit family Paridae. The genus was at one time considered as a subgenus of Parus. In 2005 an article describing a molecular phylogenetic study that had examined mitochondrial DNA sequences from members of the tit family, proposed that a number of subgenera including Cyanistes be elevated to genus status. This proposal was accepted by the International Ornithologists' Union and the British Ornithologists' Union.
Species
The genus contains three species:| Image | Scientific name | Common name | Distribution |
| Cyanistes caeruleus | Eurasian blue tit | Europe | |
| Cyanistes teneriffae | African blue tit | northern Africa and the Canary Islands. | |

The name Cyanistes was introduced for a subgenus by the German naturalist Johann [Jakob Kaup|Jakob Kaup] in 1829. The word comes from the classical Greek kuanos meaning dark-blue. The type species was designated as the Eurasian blue tit by George Gray in 1842.
