Hawks are a group of medium-sized diurnal birds of prey of the family Accipitridae which are widely distributed and varying greatly in size.

The terms accipitrine hawk and buteonine hawk may be used to distinguish the two types, in regions where hawk applies to both. The term "true hawk" is sometimes used for the accipitrine hawks, in regions where buzzard is preferred for the buteonine hawks.

All these groups are members of the Accipitridae family, which includes the hawks and buzzards as well as kites, harriers and eagles. Some authors use "hawk" generally for any small to medium Accipitrid that is not an eagle.

The common names of some birds include the term "hawk", reflecting traditional usage rather than taxonomy, such as referring to an osprey as a "fish hawk" or a peregrine falcon as a "duck hawk".

Falconry was also called "hawking", and any bird used for falconry could be referred to as a hawk.

Aristotle listed eleven types of ἱέρακες (hierakes, hawks, singular ἱέραξ hierax): aisalōn (merlin), asterias, hypotriorchēs, kirkos, leios, perkos, phassophonos, phrynologos, pternis, spizias, and triorchēs. Pliny numbered sixteen kinds of hawks, but named only aigithos, epileios, kenchrēïs (kestrel), kybindis, and triorchēs (buzzard).

The accipitrine hawks generally take birds as their primary prey. They have also been called "hen-hawks", or "wood-hawks" because of their woodland habitat.

The subfamily Accipitrinae contains Accipiter; it also contains genera Micronisus (Gabar goshawk), Urotriorchis (long-tailed hawk), and Megatriorchis (Doria's goshawk). Melierax (chanting goshawks) may be included in the subfamily, or given a subfamily of its own.
