Kairui-Midiki (also known simply as Midiki or Kairui, or Hoso by its speakers) is a language of East Timor spoken by 18,600 people in 2015, primarily in Venilale Administrative Post in Baucau, parts of the Viqueque Municipality, and suco Kairui (Manatuto Municipality).

These four varieties' level of mutual intelligibility has led some to categorize them as dialects of a single language: Kawaimina.

[2] Kairui and Midiki were listed separately in the Timor-Leste 2010 Census, but are often considered dialects of a single language, in the literature named Kairui-Midiki.

[3] According to some sources Kairui is spoken in and around the village of that name in Manatuto, and Midiki is heard in of Lacluta, Liaruca, Uai-Mori, and Venilale.

However in some districts the names Midiki, Kairui, and Hoso are used interchangeably.
