Sango (also spelled Sangho) is the primary language spoken in the Central African Republic and also the official language of the country. It is used as a lingua franca across the country and had 450,000 native speakers in 1988. It also has 1.6 million second language speakers.

Sango is a creole based on the Northern Ngbandi language. It was used as a trade language along the Ubangi River prior to French colonisation in the 1880s. In colloquial speech 90% of the language's vocabulary is Ngbandi based, whereas in more technical speech French loanwords constitute the majority.

Sango is a language with contested classification, with some linguists considering it a Ngbandi-based creole, while others argue that the changes in Sango structures can be explained without a creolization process. It is an African-based creole with French loanwords, but its structure remains wholly African. Sango was used as a lingua franca along the Ubangi River before French colonization in the late 1800s and has since expanded as an interethnic communication language.

Today, Sango is both a national and official language of the Central African Republic, spoken by 350,000 speakers as of the 1970 census. It is also spoken as a lingua franca in southern Chad and the Democratic Republic of the Congo. Sango has three distinct sociolinguistic norms: an urban "radio" variety, a "pastor" variety, and a "functionary" variety spoken by learned people who make the highest use of French loanwords.

Sango is a tonal language with subject-verb-object word order, and its orthography was officially established in 1984. It has limited written material, mainly focused on religious literature. Sango is considered easy to learn, although reaching true fluency takes time, as with any other language. The main difficulties for English speakers are pronunciation and tone management, as Sango is a tonal language.
