The breeding range of the Mascarene martin is restricted to three islands. Madagascar has an area of , but the next largest island, Réunion, is just 2,512 km2 (790 km2). Although this bird has a limited range, it is abundant on Mauritius and Réunion, and locally common in Madagascar. The population is unknown, but exceeds the vulnerability threshold of 10,000 mature individuals and is believed to be stable. This martin is therefore also classed as a species of Least Concern by the International Union for Conservation of Nature.
