The flag and the coat of arms of Kelantan are state symbols of Kelantan, Malaysia. Like the flag of Kedah, the Kelantanese flag is red with a single charge from Kelantan's coat of arms, albeit partially.
Similar to other states of Malaysia with Malay royalties, both the flag and arms of Kelantan are influenced by Kelantanese royalties, Islam, and political and natural symbols of the state.
