Leptopelis flavomaculatus is a species of frog in the family Arthroleptidae. It is found in the lowlands eastern and southern Africa, from Mozambique north of the Save River and Zimbabwe to Malawi, eastern Tanzania (including the island of Zanzibar), and coastal Kenya. Its common names are yellow-spotted tree frog, brown-backed tree frog, brown forest treefrog, and Johnston's treefrog.
Adult males measure 44–50 mm (1.7–2.0 in) and females 60–70 mm (2.4–2.8 in) in snout–vent length. The dorsum is either uniform green with white heels, or brown with a darker, forward-pointing triangle with a blunt apex. There is a dark bar between the eyes and a dark canthal line. Young, green specimens often have yellow spots.
Leptopelis flavomaculatus is similar to Leptopelis vermiculatus but lacks the latter's vermiculated dorsum. It is also similar L. christyi but is larger and its dorsal triangle has a more blunt apex.
