Terengganu Malay is a Malayic language spoken in the Malaysian state of Terengganu all the way southward to coastal Pahang and northeast Johor. It is the native language of Terengganu Malays and highly localised Chinese Peranakan community as well as a second language among the smaller Indian minority. The language has developed distinct phonetic, syntactic and lexical distinctions which makes it mutually unintelligible for speakers from outside the east coast of Peninsular Malaysia, especially those who speak Standard Malay/Malaysian. Terengganu Malay still shares close linguistic ties with neighbouring Kelantan-Pattani and Pahang of which it forms under the umbrella term of "East Coast Peninsular Malayic languages". These similarities have often confused many people outside the region, who usually interchange Terengganu Malay with Kelantan Malay, even though there are major phonological and vocabulary differences between the two.

Terengganu, formerly spelled Trengganu or Tringganu, is a sultanate and federal state of Malaysia. The state is also known by its Arabic honorific, Dāru l-Īmān. The coastal city of Kuala Terengganu, which stands at the mouth of the broad Terengganu River, is both the state and royal capital as well as the most populous city in Terengganu. Other major cities and towns includes Jerteh, Kuala Dungun, Chukai, Kuala Berang, Marang, and Permaisuri. At 13,035 square kilometres in size and a population of over 1.2 million people in 2023, Terengganu is Malaysia's 7th largest state by area and 10th largest in population. Terengganu, along with Kelantan, Perlis and the Federal Territory of Putrajaya is one of the most homogeneous states/territories in the country of which 95% of the population are ethnic Malay-Muslims with its own distinct language/dialect, culture, history and tradition.
