毒漆藤（学名：Toxicodendron radicans或Rhus toxicodendron），又名三叶毒藤，是一种分布在美国加利福尼亚州的有毒植物，在北美及澳大利亚都有分布。

Toxicodendron radicans, commonly known as eastern poison ivy or poison ivy, is a poisonous Asian and North American flowering plant that is well known for causing an itching, irritating, and sometimes painful rash in most people who touch it, caused by urushiol, a clear liquid compound in the plant's sap. The species is variable in its appearance and habit, and despite its common name it is not a true ivy (Hedera). Toxicodendron radicans is commonly eaten by many animals, and the seeds are consumed by birds, but poison ivy is most often thought of as an unwelcome weed.
