Trilepidea is an extinct monotypic genus of flowering plants belonging to the family Loranthaceae.

[4] Its native range was New Zealand.

[4] The only species was Trilepidea adamsii, or Adams mistletoe.

[1] It was first described in 1880 as Loranthus adamsii and has ever only been collected from a few locations in the North Island.

It has been argued that the extinction of this species, vulnerable due to restricted distribution, was caused by interaction of a number of factors, including introduction of an exotic species, in this case the brushtail possum from Australia.
