Thlaspi, or pennycress, is a genus of herbs of temperate regions of the Eurasian continent. They occur in Central and South Europe, South-West Asia and two species are endemic to China. The Thlaspi has been proven to be a hyperaccumulator of heavy metals such as zinc and cadmium and therefore may be used in phytoremediation initiatives.

Nine species are accepted.
It is proposed that phytoremediation using Thlaspi caerulescens would be entirely feasible for low levels of cadmium.
