Prostanthera marifolia, commonly known as Seaforth mintbush, is a critically endangered shrub which is endemic to New South Wales, Australia. The species was thought to be extinct until it was rediscovered in 2001.
Prostanthera marifolia has an erect and open habit, growing to about 30 cm high. The leaves are ovate, but often appear triangular in outline due to recurved edges. They are 8 to 12 mm long and 4 to 6 mm wide. The purple or mauve flowers appear in the leaf axils throughout the year and are about 9 to 12 mm long.
The species was formally described in 1810 by botanist Robert Brown based on plant material collected on the north shore of Port Jackson.
Prostanthera marifolia occurs in woodland near Sydney. Associated tree species include Eucalyptus sieberi and Corymbia gummifera.
The name has been missaplied to Prostanthera junonis.
