Hyperolius swynnertoni is a species of frog in the family Hyperoliidae. It is found in the southern portion of the eastern Zimbabwe uplands and adjacent Mozambique. It is also known as the Swynnerton's reed frog, with the subspecies "broadleyi " (if recognized) as the Broadley's tree frog or Broadley's forest treefrog.
Adult males reach 32 mm (1.3 in) and adult females 35 mm (1.4 in) in snout–vent length; it is among the larger Hyperolius species. The dorsal colour pattern in the type series consists of dark vermiculations on a pale background, or sometimes pale stippling on a dark background. Hyperolius marmoratus broadleyi, which may or may not be synonymous with this species, has a light mid-dorsal band running the whole length of the animal, and a pair of dorso-lateral light bands running from edge of upper eyelid and upper half of eye to base of leg. The latter are laterally bordered by a dark band. The light bands have usually a red line in the centre and are separated by a broad dark band running from canthus rostralis over upper eyelid almost to vent. These patterns are variable even within populations, including the bands curving or breaking into discontinuous lines or spots.
