The name Poison oak refers to various species of the genus Toxicodendron that grow in North America:

  • Western Poison-oak (Toxicodendron diversilobum or Rhus diversiloba), found only on the Pacific Coast of North America, ranging from southern Canada to Baja California
  • Atlantic Poison-oak (Toxicodendron pubescens or Rhus toxicarium), which grows mostly in sandy soils in eastern parts of the United States
