Ansonia mcgregori is a species of toad in the family Bufonidae. It is endemic to central and western Mindanao, Philippines. The specific name mcgregori honors Richard Crittenden McGregor, an Australian ornithologist who collected the holotype. Common names McGregor's toad, McGregori's river toad, and McGregor's stream toad have been coined for it.
Adult males measure 32–39 mm (1.3–1.5 in) and adult females 43–50 mm (1.7–2.0 in) in snout–vent length. The tympanum is not visible. All the finger tips are rounded and have small discs, not wider than rest of the phalanges. The toes are almost fully webbed. The hind legs have crossbars. The adult males have a subgular vocal sac.
