Arosi is an Austronesian language spoken by about 7000 people on the northwest end of Makira, an island in the Solomon Islands. Makira was known previously as San Cristobal or San Cristoval, and until the 1880s, was called Bauro by the Melanesian Mission. David Griffiths, in his Bibliography of the Book of Common Prayer, lists Arosi and Bauro as two of five dialects of the San Cristoval language, while Ethnologue has five different languages (including Arosi, Bauro, and Owa) spoken on this island.

A large number of Anglican publications have been produced for use on Makira. Those in Arosi include the following; the last three texts are presented here:
