Hartwrightia is a genus of North American flowering plants in the tribe Eupatorieae of the family Asteraceae. The genus contains a single species, Hartwrightia floridana, native to the US states of Georgia and Florida. The species is sometimes referred to by the common name Florida hartwrightia.

Although superficially similar to some species in Eupatorium, it can be distinguished by having a basal rosette of leaves, flowers of a different shape, and the fruit which lacks the parachute-like pappus found in Eupatorium. The plant is about one meter tall. It flowers in the fall and the flowers are white to pink or blue.

The genus is named for plant collector Samuel Hart Wright, 1825–1905.
