Ralfsia is a genus of crustose brown seaweed in the family Ralfsiaceae..

The genus name of Ralfsia is in honour of John Ralfs (1807–1890), who was a British doctor and mycologist.

The genus was circumscribed by Eugene O'Meara in Proc. Roy. Irish Acad. ser.2, vol.2: on pages 293, 419 in 1875.

Plowrightia mereschkowskyi is lichenicolous fungus (a parasite on living lichens) (on Aspicilia hispida).
