刚果语 (也写作Kikongo) 是班图语支中生活在刚果民主共和国、刚果共和国和安哥拉热带雨林的Bakongo和Bandundu族人使用的语言。这是一种声调的语言，由此产生了吉土巴语，一种班图语支的克里奥耳语和通行于中部非洲西部的通用语。很多从非洲这个地区作为奴隶被贩卖到美洲的人也说这种语言。因此，尽管刚果语在上述国家使用，类似克里奥耳语的语言仍然可以在巴西, 牙买加, 古巴，特别是海地的源自非洲的宗教仪式中找到。它也是哥伦比亚的克里奥耳人的帕伦克语和嘎勒族人的语言的来源之一。绝大多数说这种语言的人生活在非洲，粗略估计在刚果有700万人使用刚果语做为母语，可能有200万或者更多人把它作为第二语言。

Kongo or Kikongo is one of the Bantu languages and is spoken by the Kongo and Ndundu people living in the tropical forests of the Democratic Republic of the Congo, the Republic of the Congo and Angola. It is a tonal language. It was spoken by many of those who were taken from the region and sold as slaves in the Americas. For this reason, while Kongo still is spoken in the above-mentioned countries, creolized forms of the language are found in ritual speech of Afro-American religions, especially in Brazil, Cuba, and Haiti. It is also one of the sources of the Gullah language and the Palenquero creole in Colombia. The vast majority of present-day speakers live in Africa. There are roughly seven million native speakers of Kongo, with perhaps two million more who use it as a second language.
