Fuelleborn's stream frog or long-toed grass frog (Strongylopus fuelleborni) is a species of frog in the family Pyxicephalidae. It is found in the mountains of Malawi, Tanzania, and northeastern Zambia. Its natural habitats are montane grasslands at elevations of 1,500–3,000 m (4,900–9,800 ft) above sea level. Outside the breeding season, it can be found far from water. During the breeding season, males call from flooded grass. The egg clusters are laid just above streams, underneath dense vegetation. Tadpoles develop in the streams.
