Cyanea citrea is a species of true jellyfish in the family Cyaneidae.

[2] The generic name, Cyanea, is derived from the Latin cyaneus, meaning "deep or dark blue in color".

The specific epithet, citrea, is derived from the Latin citreus, meaning "citrus", likely in reference to the species' orange color.

The species' tentacles are grouped in eight U-shaped tracts, and are a reddish color at parts distanced from the body.

Male genital glands are a light orange-yellow color, while those of females are a dark yellow-brown.
