The Sumba–Flores languages, which correspond to the traditional "Bima–Sumba" subgroup minus Bima, are a proposed group of Austronesian languages (geographically Central–Eastern Malayo-Polynesian languages) spoken on and around the islands of Sumba and western–central Flores in the Lesser Sundas, Indonesia. The main languages are Manggarai, which has half a million speakers on the western third of Flores, and Kambera, with a quarter million speakers on the eastern half of Sumba Island.

The Hawu language of Savu Island is suspected of having a non-Austronesian substratum, but perhaps not to any greater extent than the languages of central and eastern Flores, such as Sika, or indeed of Central Malayo-Polynesian languages in general.

Blust (2008)^[1] finds moderate support for linking the languages of western and central Flores with Sumba–Hawu.
