Megarhabda is a genus of beetles belonging to the family Chrysomelidae.

Diagnosis This genus is quite different from Trirhabda (the genus in which the single named species of Megarhabda was previously placed). Among other things, the pronotum of Megarhabdais is very short (about 2.5 times as broad as long). In this respect, the new genus is similar to Derospidea, but differs in the larger pronotal depressions and the more broadly explanate lateral pronotal margins

Etymology The genus name suggests a relationship to Trirhabda, but with unusually large size.
