Eucarpha is a genus of flowering plant of the family Proteaceae, endemic to New Caledonia. Two species are recognised. Up until 1975, these were classified within the genus Knightia until Lawrie Johnson and Barbara G. Briggs recognised their distinctness, particularly their prominent bracts, in their 1975 monograph "On the Proteaceae: the evolution and classification of a southern family". As of today, the nomenclatural combinations for these two species in the genus Eucarpha have not been published.
