Ringwood is a hamlet in York Region, Ontario, Canada, in the Town of Whitchurch–Stouffville. The hamlet is centred at the intersection of Stouffville Road and Highway 48, on the Little Rouge River, a tributary of the Rouge River on the Oak Ridges Moraine. The community originally straddled the townships of Markham and Whitchurch in the County of York. The hamlet was named Ringwood in 1856 by George Sylvester, postmaster and owner of a general store, after the town of Ringwood, in Hampshire, England. It was first settled in the 1790s by George Fockler from Pennsylvania. The Little Rouge River runs along the eastern edge of the hamlet. In 1857, Ringwood had a population of 200 which grew only slightly to 225 by 1910. By 1972, the population had dropped to 172.
