契维语 (Twi，发音为： 'chwee' [tɕʷi]，又译特威语和多威语)是一种在西非加纳通行的语言，使用人口约830万人。 它是阿坎语族的一种方言，属于尼日尔-刚果语系大西洋刚果亚语系沃尔塔刚果语族的瓜语支。严格来说，契维语亦只是一个语言集合的名称，因为它其实包括了两种同样叫作「契维语」的阿坎语方言，分别为：阿散蒂契维语(Ashanti Twi)及阿库阿卞契维语(Akuapem Twi)，他们与方提方言(Fante dialect)共同组成了阿坎语。这三种语言间都能够互相沟通。

契维语主要在阿散蒂地区通行，另外亦有在加纳的布朗阿哈福地区、中部地区、东部地区、西部地区及沃尔特地区的部份地方通行。

Twi (pronounced [tɕɥi]) or Asante Twi, is spoken by over 9 million ethnic Ashanti people as a first language and second language. Twi (or Asante Twi) is a common name for two former literary dialects of the Akan language, Asante (Ashanti) and Akuapem, which are mutually intelligible. There are about 9 million Twi speakers, mainly in Ashanti. Akuapem Twi was the first Akan dialect to be used for Bible translation, and became the prestige dialect as a result.
