Cophixalus pulchellus is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. This species is only known from one locality on Mount Hunstein, Papua New Guinea, at 1,000m asl. It has been listed by IUCN on the Red List because it has recently been discovered, and there is very little information on the extent of its occurrence, status, and ecological requirements. Its status was assessed in 2004. It was classified as data deficient. Its population trend was unknown at its last assessment. Its population is known only from a single, discovered specimen. It was found in shrubs in closed-canopy rainforest, and the species is presumed to breed by direct development. There are no known threats to this species, and its location probably safe from human disturbance at this time.
