Romeo and the Black Brothers (ロミオの青い空, Romio no aoi sora, "Romeo's Blue Skies") is a 1995 Japanese anime series by Nippon Animation. Although "Romeo's Blue Skies" is the literal translation of the Japanese title, the official English name given by Nippon Animation is "Romeo and the Black Brothers". It is known in Arabic as "عهد الأصدقاء" (literally "Friends' Covenant"), in the Philippines as "Mga Munting Pangarap ni Romeo" (literally "Romeo's Simple Dreams"), and in Greece as "Τα Παιδιά των Καπνοδόχων" (literally "The Children of the Chimneys".)

It is based on the novel Die schwarzen Brüder ("The Black Brothers") written in 1941 in Switzerland by author Lisa Tetzner.
