Kaharuddin Datuk Rangkayo Basa (17 January 1906 – 1 April 1981) was an Indonesian police officer and politician who was the first governor of West Sumatra, serving from 1958 until his removal in 1965.
Kaharuddin was born in the nagari of Bayur, on the shores of Lake Maninjau and today part of Agam Regency, on 17 January 1906.
He received his traditional title Datuk Rangkayo Basa in April 1937 when he was serving as a deputy chief of the police in Baso, Agam [id].
