The Unfederated Malay States was a group of five Malay states, namely Johore, Terengganu, Kelantan, Kedah and Perlis. The grouping by itself was not a single entity but merely a term to describe the Malay states. The chief officer of the British colonial administration was called the "advisor".

The de facto language of Unfederated Malay States was Malay with Jawi script.
