Miniopterus newtoni is a species of bat that is endemic to São Tomé and Príncipe.

Taxonomy
Miniopterus newtoni was described as a new species in 1889 by Portuguese zoologist José Vicente Barbosa du Bocage.
The holotype had been collected by Portuguese naturalist Francisco Newton.
In the third edition of Mammal Species of the World, Simmons et al. considered M. newtoni as a subspecies of the least long-fingered bat, M. minor. 
However, in 2007, a mitochondrial DNA analysis rejected the assertion that M. minor and M. newtoni were synonymous.
Juste et al. published that M. newtoni and M. minor had a genetic distance significant enough to regard each as separate species.

Description
It has a forearm length of approximately .

Range and habitat
M. newtoni is endemic to the nation of São Tomé and Príncipe, where it has only been documented on São Tomé Island.
It has been documented in both forested habitat and plantations.

Conservation
As of 2019, it is evaluated as a data deficient species by the IUCN.
It meets the criteria for this classification due to the lack of information on its extent of occurrence and threats it may be facing.
