The Dandenong Creek (Aboriginal Bunwurrung: Narra Narrawong[1] or Dandinnong[2]) is an urban creek[3] of the Port Phillip catchment, located in the eastern and south-eastern Greater Melbourne region of the Australian east coast state of Victoria.

The creek is also the home of one of the largest remaining populations of Yarra Gum,[6] and a series of linear parks, nature reserves and wetlands are located along it.

A bike path known as the Dandenong Creek Trail runs alongside for a significant distance.

The health of the creek in these urban areas ranges from moderate to very poor and has been the focus of a number of clean-up campaigns in recent years.

[9] The tributary is commonly contaminated with plastic litterings and heavy metals, and authorities have made several attempts to prevent pollution which spreads downstream into Dandenong Creek.
