The Ikpeng language is the language of the Ikpeng people (also known as Txikāo) who live in the Xingu Indigenous National Park in Mato Grosso, Brazil. There are approximately 500 speakers (Rodgers, 2013). Ikpeng is a language with high transmission, meaning it is passed on from parent to child at a high rate, with all members speaking the language (Moore, 2006). The majority of members are also bilingual speakers of Portuguese (Pacheco, 2005). The Ikpeng language is part of the Carib (karib) language family (Moore, 2006).
