The flag of Sarawak, officially known as Ibu Pertiwi ('Motherland'), is the official flag of Sarawak, a state in Malaysia. It is based on the flag of the Raj of Sarawak of the White Rajah, and includes the yellow of Southeast Asian royalty — a similar yellow and diagonal black are in the flag of Brunei, although Brunei's yellow is of a brighter shade.
