Microhyla mantheyi (common name: Manthey's narrow-mouthed frog) is a species of microhylid frog.

It is endemic to the Malay Peninsula and occurs in southern Myanmar, southern Thailand, Peninsular Malaysia, and Singapore.

[2] However, molecular data suggest that the nominal species consists of at least two cryptic species.

[2][3] Microhyla mantheyi inhabits lowland forests and slightly disturbed areas where they are usually found on the ground or in low vegetation.
