The Misumalpan languages (also Misumalpa or Misuluan) are a small family of languages spoken by indigenous peoples on the east coast of Nicaragua and nearby areas.

Kaufman (1990) finds a connection with Macro-Chibchan to be "convincing", but Misumalpan specialist Ken Hale considered a possible connection between Chibchan and Misumalpan to be "too distant to establish".

[2] Miskito became the dominant language of the Mosquito Coast from the late 17th century on, as a result of the people's alliance with the British Empire, which colonized the area.

Its sociolinguistic status is lower than that of the English-based creole of the southeast, and in that region, Miskito seems to be losing ground.

Sumo is endangered in most areas where it is found, although some evidence suggests that it was dominant in the region before the ascendancy of Miskito.
