Brachyrhaphis roseni, commonly known as the cardinal brachy, is a poeciliid fish from Costa Rica.

B. roseni grows to 6 cm. The fish have a slightly arched body and twelve dark vertical stripes, which are normally more prominent in males. The dorsal fin is half orange with a dark margin. The caudal fin has an orange edge; in males there is also a dark band before the edge. There are commonly dark stripes near the base of the fin. The anal fin is yellowish with a dark blotch. B. roseni is similar to the related species B. rhabdophora.

B. roseni lives in stagnant and slow to moderately fast flowing waters. It may be found on the surface or in the midwaters. Its habitats are between 20 and 100 m above sea level, and the water temperature ranges from 22 to 30 °C. It is distributed along the Pacific slope of Central America, from the drainage of the Coto Colorado River in Costa Rica to the Santa María River in western Panama. It is rare in the south of Costa Rica. In the north it is replaced by B. rhabdophora and in the south by other Brachyrhaphis species.
