Mwotlap (pronounced [ŋ͡mʷɔtˈlap]; formerly known as Motlav) is an Oceanic language spoken by about 2,100 people in Vanuatu. The majority of speakers are found on the island of Motalava in the Banks Islands, with smaller communities in the islands of Ra (or Aya) and Vanua Lava, as well as migrant groups in the two main cities of the country, Santo and Port Vila.

Mwotlap was first described in any detail in 2001, by the linguist Alexandre François.

Volow, which used to be spoken on the same island, may be considered a dialect or a separate language.

The Mwotlap language is named after the island of Motalava, which is locally known as Mwotlap.

Mwotlap is spoken by about 2,100 people in the Banks Islands, in the North of Vanuatu. Among them, 1,640 live on the island of Mota Lava and its neighbor island, Ra. It is also spoken by a few hundred people living elsewhere in Vanuatu:

Mwotlap belongs to the Torres–Banks linkage within Southern Oceanic, one of the subgroups of the Oceanic family, itself part of the larger Austronesian phylum.

Robert Henry Codrington, an Anglican priest who studied Melanesian societies, first described Mwotlap in 1885. While focusing mainly on Mota, Codrington dedicated twelve pages of his work The Melanesian Languages to the "Motlav" language. Despite being very short, this description can be used to show several changes that occurred in Mwotlap during the 20th century, such as the change of r to y (a process demonstrated already in the loanword Epyaem 'Abraham'). Furthermore, Codrington described Volow, a language closely related to Mwotlap (sometimes even considered a dialect of Mwotlap). Volow, which is extinct today, was spoken in the east of Mota Lava, in the area of Aplow.

Because Mwotlap has been passed down by oral tradition, it has no official writing system. This article uses the orthography devised by linguist Alexandre François, based on the Latin alphabet.
