The name Dandenong is derived from the Woiwurrung language of the Wurundjeri people, that was applied to the watercourse now known as Dandenong Creek. The name has been appropriated to extend beyond its actual meaning and is now applied to two settlements, a mountain summit and the Dandenong Ranges mountain range. The creek however, originates in the mountain range, so this connection is more understandable.

It is not known where the name Dandenong came from nor what it means, or even its correct spelling, other variations include; Tanjenong, Tangynon and Bangeong. In any case, the name relates at least to watercourses in general, and not to mountains or ranges, as indicated by the ong ending.
