Osteocephalus mutabor is a frog in the family Hylidae. It lives in Ecuador and Peru. It lives in the hills on the west side of the Andes mountains. Scientists have seen it between 250 and 1000 meters above sea level.
The adult male frog is 35.6–50.3 mm long from nose to rear end and the adult female frog is 52.7–75.7 mm long.
This frog is brown or green-brown in color with marks across its back. Its belly is pink, orange, or whitish. The adult male frogs have bumps on their backs.
The female frog lays 30-40 eggs at a time.
