Napeca (Nape, Napeka) is an extinct Chapacuran language. The Napeca people were said to have spoken the same language as those who spoke Quitemoca, and is thought to be a dialect of the same language as Quitemoca. Jürgen Riester documented the language in the 1960s, and recorded some samples.
The suffix is sometimes attached after an adjective to indicate the first person singular (e.g. 'I am well', literally "healthy-I"); the same construction is present for the second person singular (e.g. 'you are well', literally "healthy-you").
Negation is expressed in Napeka by the infix .
