Thalictrum is a genus of 120-200 species of herbaceous perennial flowering plants in the Ranunculaceae (buttercup) family native mostly to temperate regions.

Thalictrum is a taxonomically difficult genus with poorly understood species boundaries; it is in need of further taxonomic and field research for clarification.

Despite their common name of "meadow-rue", Thalictrum species are unrelated to the true rue (family Rutaceae), but resemble its members in having the petiole twice or thrice divided.
