Waldeck (also known as Pageant or Wheat Centre) is an unincorporated community in Vulcan County, Alberta, Canada. The former community site is located 12km (07miles) south of the Village of Milo, on the eastern shore of McGregor Lake at the intersection of Township Road 180 & Range Road 214. Waldeck has suffered from depopulation since the mid-1920s and very little remains of the original townsite. However, many cabins and recreation homes have recently been built along the lake at the site.
The community was named by the Canadian Pacific Railway.
