Rhododendron is an unincorporated community in Clackamas County, Oregon, United States. It is located within the Mount Hood Corridor, between Government Camp and Zigzag on U.S. Route 26. It is one of the communities that make up the Villages at Mount Hood.A post office was established in the area in 1909 and named "Rowe" after Henry S. Rowe, a mayor of Portland, Oregon who was interested in developing the state's scenic attractions. In 1917 the office was renamed "Zig Zag" and shortly thereafter "Zigzag". In 1920 the office was renamed "Rhododendron" because of the large number of rhododendrons growing near there. The community started out as a summer resort colony, but with the increased popularity of skiing, it became a year-round settlement.
