Ligusticum is a genus of flowering plants in the family Apiaceae. Its name is believed to derive from the Italian region of Liguria.

The roots of two species are used as medicinal herbs: L. wallichii (Chinese: 川芎; pinyin: chuānxiōng) is used in traditional Chinese medicine and L. porteri (Osha) is used in Western herbal medicine.

Ligusticum species are used as food plants by the larvae of some Lepidoptera species including Mouse Moth which has been recorded on L. scoticum.
