Garnieria is a monotypic plant genus in the family Proteaceae.

Molecular phylogenetic studies indicate that it is nested in the larger Australian genus Persoonia where it may be included.

[1] It is endemic to New Caledonia where the type specimen was collected at Prony Bay in 1868–1870 by Benjamin Balansa.

[2] The plant grows as a shrub up to 2 m in height, sometimes a small tree up to 4 m. Its shiny leaves are dark green above, paler below.

The fruits are green at first, becoming dark crimson to brown.
