Taba (also known as East Makian or Makian Dalam) is a Malayo-Polynesian language of the South Halmahera–West New Guinea group. It is spoken mostly on the islands of Makian, Kayoa and southern Halmahera in North Maluku province of Indonesia by about 20,000 people.

There are minor differences in dialect between all of the villages on Makian island in which Taba is spoken. Most differences affect only a few words. One of the most widespread reflexes is the use of /o/ in Waikyon and Waigitang, where in other villages /a/ is retained from Proto-South Halmaheran.

As of 2005, Ethnologue lists Taba as having a speaking population of approximately 20,000; however, it has been argued by linguists that this number could in reality be anywhere between 20,000 and 50,000. The language is predominantly spoken on the eastern part of Makian Island, although it is also found on the southern island of Mori, Kayoa, Bacan, and Obi, and along the west coast of south Halmahera. There has also been continued migration of speakers to other areas of North Maluku due to frequent volcanic eruptions on Makian Island. The island itself is home to two languages: Taba, which is spoken on the eastern side of the island, and a Papuan language spoken on the western side, known alternatively as West Makian or Makian Luar (Outer Makian); in Taba, this language is known as Taba Lik ('Outer Taba'), while its native speakers know it as Moi.

Taba is divided into three different levels of speech: alus, biasa, and kasar.

The alus, or 'refined' Taba, is used in situations in which the speaker is addressing someone older or of greater status than the speaker themselves.

The biasa, or 'ordinary' Taba, is used in most general situations.

The kasar, or 'coarse' form of Taba, is used only rarely and generally in anger.

Taba has fifteen indigenous consonant phonemes, and four loan phonemes: /ʔ dʒ tʃ f/. These are shown below:
