Precis is a genus of nymphalid butterflies that Jacob Hübner described in 1819. They are commonly known as commodores and are found in Africa. Two species are endemic to Madagascar.

Precis are medium-to-large butterflies (wingspan up to 5 cm). The upperside ground colour is black with white, pink, green, or blue spots and bands, the upperside may also have a brownish ground colour. The wings often have eyespots. The outer wing margins are wavy and toothed or scalloped. Several species occur in multiple colour forms (morphs). They tend to have distinct rainy-season and dry-season forms, that of the gaudy commodore being the most extreme. Transitional forms are also known.

Precis are savannah species. They are good fliers. The larvae feed on Lamiaceae.

The genus Precis is closely allied to Junonia. The two genera differ in the structure of their genitalia and larval food plant choice. The type species of the genus is Precis octavia.
