The Tai forest tree frog, Leptopelis occidentalis, is a species of frog in the family Arthroleptidae. It is found in Liberia, southern Ivory Coast, and Ghana. Records from Nigeria are controversial and may refer to other species, possibly Leptopelis boulengeri.
Males measure 36–46 mm (1.4–1.8 in) and females 49–72 mm (1.9–2.8 in) in snout–vent length. There are two colour phases. In phase A, the dorsum is green, either uniform or with minute, white spots. In phase B, the dorsum is brown and has a darker, n-shaped pattern, or in some cases, a triangular pattern, with the apex pointing forward. There is often a small whitish spot just below the eye.
Males of this species can quite often be heard calling in small groups high up in bushes and trees or large clumps of bamboo. The call is a rather soft "düt" with a very peculiar acoustical quality. The call is also described as a "typical Leptopelis clack call".
