Totness Recreation Park (formerly Totness National Parks Reserve) is a protected area in the Australian state of South Australia located within the localities of Mount Barker and Totness in the central Mount Lofty Ranges. Covering 41 hectares (101 acres) of land, the park is divided by the South Eastern Freeway and features a large dam. It was declared as a reserve in 1970 and re-designated as a recreation park in 1972. The park has no visitor facilities except for access tracks. It is the only park in the district, managed by the Department of Environment and Water, that is solely designated for recreation.
