The Calvary Wakefield Hospital, formerly Private Hospital, Wakefield Street (PHWS) and variants, Wakefield Street Private Hospital, Wakefield Memorial Hospital and Wakefield Hospital, referred to informally as "the Wakefield", was a private hospital founded in 1883 or 1884 on Wakefield Street in Adelaide, South Australia. In 1935, the hospital occupied new, purpose-built premises on the corner of Wakefield and Hutt Streets. In 2006 it was acquired by Little Company of Mary Health Care Ltd., known as Calvary Health Care, a Roman Catholic not-for-profit organisation. In 2020 it was vacated, being replaced by a newly constructed facility, the Calvary Adelaide Hospital. The hospital provided acute care with inpatient and outpatient facilities, orthopaedic, and neurosurgical services to patients. It specialised in cardiac care, and was the only private 24/7 accident and emergency unit in the city. It employed 600 staff.
