Leptopelis yaldeni is a species of frog in the family Arthroleptidae. It is endemic to Ethiopia and occurs in the montane highlands in Gojjam. Its range might be limited by the deep gorges of the Blue Nile. It is named in honour of Derek Yalden, a British zoologist who collected some of the types. Common names Yalden's tree frog and grassland forest treefrog have been coined for this species.

starts withAdult males measure 26–34 mm (1.0–1.3 in) and adult females 38–43 mm (1.5–1.7 in) in snout–vent length. The habitus is relatively slender. The snout is moderate, slightly pointed in profile. The tympanum is round and fairly conspicuous. Digital discs are of moderate size. The webbing between the toes and the two outermost fingers is moderate.
This species has two colour morphs. One form is dorsally brown (ranging from pale cream or golden, sometimes greenish, through shades of grey-brown or red-brown to dark purplish-brown), typically with darker markings with that may be prominent; the pattern includes an often incomplete interorbital bar and a triangular dorsal mark. The other morph is bright green (bright blue-green or yellow green, rarely silver-green or pale to dark olive); dorsal markings are usually absent. The green form dominates at the upper end of the altitude range of this species where the habitats are more open, whereas the brown morph is only present at lower altitudes where the habitat has more cover.
The male advertisement call is a series of screams followed by a click.
The tadpole have a short, deep body and relatively long tail. The largest specimen, with budding hindlimbs, measures 67 mm (2.6 in) in total length.
