Windellama () is a rural locality in the Southern Tablelands of New South Wales, Australia in the Goulburn Mulwaree Council. It is northeast of Canberra and southeast of Goulburn. At the 2021 census, it had a population of 417. Windellama is a popular location for people from Sydney to make a "tree change". This has created a change in property sizes in the area, previously mostly large agricultural enterprises, now on a multitude of 50-100 acre (20-40 ha)hobby farms.
It has a strong community with its own local monthly newspaper the "Windellama News", an active Historical Society, Progress Association, monthly farmer's market, Windellama Public School Parents and Citizens Association and Rural Fire Brigade.
