Psoralea cataracta is a species of flowering plant in the family Fabaceae.

It was declared extinct in 2008 in the Red List of South African Plants, with a single specimen collected from the Tulbagh Waterfall in 1804.

It was rediscovered 200 years later by Brian Du Preez in November of 2019 in the Winterhoek Mountains near Tulbagh.

[4] Psoralea cataracta is found around the southern slopes of the Winterhoek Mountains in the Tulbagh Valley.

[1] As of the 2022 classification, Psoralea cataracta is classified as Critically Endangered due to its restricted extent of occurrence and area of occupancy of less than 8 km2, the threat of alien invasive species such as Acacia mearnsii and species of Pinus, and the expansion of farmland in the Winterhoek Mountains.
