The Wallacean drongo has a very large range and does not approach the thresholds for Vulnerable under the range size criterion. Its extent of occurrence is greater than 20,000 km2. The population trend is not known but it is not believed to be declining sufficiently rapidly, and the population size is believed to be large enough for it to not qualify as Vulnerable using the population size criterion. For these reasons the species is classified as Least Concern by the IUCN.
