Sembrouthes was a King of the Kingdom of Aksum who most likely reigned sometime in the 3rd century.

He is known only from a single inscription in Greek that was found at Dekemhare (ደቀምሓረ ድንበዛን), Hamasien in modern-day Eritrea, which is dated to his 24th regnal year.

[2] His inscription reads as: Discussing the evidence provided in the inscription and the absence of any coins issued with his name of them, Munro-Hay concludes that Sembrouthes "finds better into the earlier part of the Aksumite royal sequence.

[4] In his later history of Aksum, Munro-Hay narrowed the date of his reign to a gap between `DBH and DTWNS, or c.250.

Hahn, in a study published in 1983, assigns Sembrouthes to the 4th century, between Aphilas and Ezana.
