The Aero A.38 was a Czechoslovakian biplane airliner of the 1920s and 1930s.

Following the relatively modern A.35, this aircraft was something of a throwback, marrying a fuselage derived from the A.35 to wings copied from the A.23.

A few served with CSA, and others with French airline Compagnie Internationale de Navigation Aérienne.

These latter aircraft were powered by a French Gnome-Rhône engine instead.
