Gaeana (from Sanskrit: गायन, romanized: gāyana, lit. 'singer') is a genus of cicadas, most members of which have colourful marking on their forewings, found across tropical and temperate Asia. Their bright wing patterns have been hypothesized as being a case of Batesian mimicry where the toxic models may be day-flying moths of the subfamilies Zygaeninae and Arctiinae. It was thought to be related to the genus Tosena but is differentiated by the exposed tympanum and lacks spines on the sides of the pronotum and now in a separate tribe.

Some species like G. maculata have been found to show a great deal of patterning variability across geography.
