Nieuwesteeg Heritage Rose Garden is a collection of rare and unusual roses, mostly hybrid teas, bred in the early 20th century. It is located in Maddingley Park, Bacchus Marsh, a town and suburb some 50 kilometres (30 mi) west of Melbourne and 14 kilometres (9 mi) west of Melton. The rose garden was established from 2009, with stock donated by rosarian John Nieuwesteeg.
