Ronald Edward Frederick Kimera Muwenda Mutebi II (born 13 April 1955) is the reigning Kabaka of the Kingdom of Buganda, a kingdom in modern-day Uganda. He is the thirty-sixth (36th) Kabaka of Buganda.

Since the restoration of the Ugandan Kingdoms, the Kabaka's position is as Ssabataka (Head of the Clans) and as the cultural leader of the 7.5 million Baganda both in Buganda and in the Diaspora. Most of the Kabaka's time and efforts since his crowning have been directed at restoring Buganda's institutions, customs, cultural practices, and behaviors. He has played a leading role in inspiring the confidence of his subjects not to abandon the practices that have made the Kingdom endure over the last 800 years.
