Rusubbicari was a Phoenician and Carthaginian colony and Roman town. It has been tentatively identified with ruins at Zemmouri El Bahri, Algeria. The Roman town was in the province of Mauretania Caesariensis.

The present name is a masculine plural noun, suggesting it may have originally consisted of two or three separate settlements. It seems to a latinization of a Phoenician name including the element rush (Punic: 𐤓‬𐤀𐤔‬, RʾŠ, "cape") and a local Berber placename.

Rusubbicari was a Christian bishopric in late antiquity and is a Catholic titular see (Latin: Dioecesis Rusubbicarensis).
