Foodo (ISO 639-3 fod) is a Guang language spoken in and around the town of Sèmèrè in the north of Benin. There are approximately 37,000 speakers (taking the most recent estimate and adding the estimated 3.2% a year growth rate for Benin). A large proportion of the population live beyond the homeland in other parts of Benin, as well as in neighboring Togo, Nigeria, and Ghana. There may be as many as 1,000 living in Ghana.

The language has its origin in Ghana. Approximately 200 to 300 years ago, a group of Guang speakers migrated from the south of Ghana to Sèmèrè along the ancient cola trade route which extended through Togo and Benin to Nigeria. The various origins of Foodo speakers are still retained in clan names."

Foodo is one of the national languages of Benin. In the Beninese sociopolitical context 'national language' is interpreted to mean all African languages spoken within the borders of the country.

The Foodo have close historical and cultural links through Islam to the Tem (often known as Kotokoli), in and around the town of Sokode in Togo. Many Foodo are bilingual in Tem as a trade language.

Foodo has 24 consonant phonemes. Consonants in parentheses are found only in loan words.

Like other Guang languages, Foodo has nine phonemic vowels. Vowel length is contrastive, resulting in a total of 18 vowels.

Foodo is a tonal language, meaning that pitch differences are used to distinguish one word from another. These contrasts may be lexical or grammatical.

There are two tones, High (H) and Low (L).
