鱼藤属（学名：Derris）是豆科下的一个属，为稀直立灌木或小乔木植物。该属共有70余种，分布于热带地区。此属植物的根部含有鱼藤酮，是一种天然杀虫剂及鱼毒。

Derris is a climbing leguminous plant of Southeast Asia and the southwest Pacific islands, including New Guinea. Its roots contain rotenone, a strong insecticide and fish poison.

Also known as derris powder and tuba root, it was formerly used as an organic insecticide used to control pests on crops such as peas. However, due to studies revealing its extreme toxicity, as well as due to the concentration level of rotenone to which the powder is often refined, experts in ecological and organic growing no longer consider it ecologically sound. Rotenone is still sold in the U.S., however.
