Legana is a small township on the Tamar River in northern Tasmania, Australia. It is 12 kilometres north of Tasmania's second largest city, Launceston. It is adjacent to Riverside, Bridgenorth, Grindelwald and Rosevears. At the 2006 census, Legana had a population of 2,500.
The name "Legana" is based on the Aboriginal word for "fresh water" since it is at the point where the Tamar River becomes fresh water. There is currently a homestead called "Freshwater" which was adjacent to a private jetty where early settlers traded with the local natives. This homestead, in Nobelius Drive, now operates as a Bed and Breakfast accommodation house.
