Philautus mjobergi is a species of frog in the family Rhacophoridae.

It is endemic to northern Borneo and found in Kalimantan (Indonesia) and Sarawak (Malaysia).

[1][2] The specific name mjobergi honours Eric Mjöberg, a Swedish naturalist, ethnographer, and explorer.

The dorsal ground colour is pale grey to dark chestnut; the pattern is highly variable and may include bars, stripes, and mottling, or be plain.

[4] Males call at night from the shrub layer 0.15–3 m (0.5–9.8 ft) above the ground.
