Circanota undulata is a species of moth of the family Tortricidae.

It is found in Costa Rica and Panama, at altitudes below about 900 meters.

The forewings are fawn brown mixed throughout with pale orange brown, with faint, narrow, variable traces of slightly darker post-median and subterminal fasciae, and a few short darker strigulae along the costa.

There is a well developed costal fold occupying the straight basal 0.4 of the costa.

The species name refers to the undulate costa of the forewing.
