The current flag of Terengganu dates from 1953 and is solid black with a white border and features crescent and star (symbolism of Islam) in white in the center. The white border symbolizes the power of the Sultan, which protectively surrounds the people (represented by the colour black). Terengganu (like Kelantan) was originally part of Siam (Thailand). When Terengganu partially separated from Siam in 1832, a plain white flag was used. Later the flag became black, and only the first third of the flagpole remained as a white stripe. The reasons can only be speculated: The Sultan of Terengganu introduced a white personal flag, as was common practice with most Malay states. In the interest of differentiation, the national flag now had to be changed. The country's state flag or official flag (flag for offices and authorities) was distinguished by a white diagonal cross in the black field of the flag. From 1933 onwards, the crescent and star in white were added to the black field of the flag on the national flag. The official flag was now distinguished from this by inserting a crescent and star in black into the white stripes of the flag. On 1st of April in 1946, the country became a member of the Malayan Union. A little later, the national flag became superfluous due to the new federal authorities. The Malayan Union was reorganized in 1948 and became the Malay Federation under a British High Commissioner, which achieved independence from United Kingdom in 1957 as the Kingdom of Malay Federation. In 1963 the Kingdom of Malaysia was founded. The common economic and defense policy from 1948 made the naval and commercial flags of the member states superfluous. The country's provinces all have their own flags, with each province using a plain flag bunting with the respective colour of the province, which features the national flag of Terengganu in the top corner.
Terengganu does not have a coat of arms in the traditional sense, it is more of a seal, a white high oval that shows symbols of state power in its center: the Sultan's crown, sword and dagger as symbols of supreme power, two books (Quran and Kitab), and the service sash of the ladies-in-waiting. At the top, a crescent and star as symbols of Islam (the predominant religion), at the bottom, in Arabic Jawi script, the name of the country.

There are several theories about the origin of the name "Terengganu". One theory, probably the most plausible, traces the origin of the name to the Malay words "terang ganu" which means "bright rainbow".
