Negus (Negeuce, Negoose) (Ge'ez: ንጉሥ, nəgueś [nɨgueɬ]; cf. Tigrinya: ነጋሲ negus [negus]) is a title in the Ethiopian Semitic languages. It denotes a monarch, such as the Negus Bahri (king of the sea) of the Medri Bahri kingdom in pre-1890 Eritrea, and the negus in pre-1974 Ethiopia. The negus is referred to as Al-Najashi (النجاشي) in the Islamic tradition.

Negus is a noun derived from the Ethiopian Semitic root ngś (neguess), meaning "to reign". The title has subsequently been used to translate the word "king" or "emperor" in Biblical and other literature. In more recent times, it was used as an honorific title bestowed on governors of the most important provinces (kingdoms): Gojjam, Begemder, Wollo, Tigray and the seaward kingdom (where the variation Bahri Negasi "King of the Sea", was the ancient title of the ruler of present-day central Eritrea) and later Shewa.
