The Fraser Health Authority (FHA) is one of five regional public health authorities in British Columbia. It is governed by the provincial Health Authorities Act. Between Aug. 1, 2017, and July 31, 2018, Fraser Health performed over 91,000 surgeries and postponed nearly 2,300 operations on the day of surgery.

Fraser Health was created in December 2001 as part of a province-wide restructuring of health authorities by the then-new BC Liberal government of Premier Gordon Campbell. It is the merger of three former health regions: Simon Fraser Health Region (SFHR), South Fraser Health Region, and the Fraser Valley Health Region (FVHR).

SFHR had been formed in 1996 by the merger of the Fraser–Burrard Hospital Society (Royal Columbian Hospital, Eagle Ridge Hospital and Ridge Meadows Hospital) with the Burnaby Health Region (Burnaby Hospital) and the extended care facilities operated by the Pacific Health Care Society (Queen's Park Care Centre and Fellburn Care Centre).

It has 29,000 employees and serves the region from Boston Bar in the Fraser Canyon down the Fraser River Valley to the Vancouver suburbs of Burnaby and Delta. It is the largest health authority by population in British Columbia (BC). Its 1.9 million residents include approximately 62,000 Indigenous people associated with 32 First Nation bands and 5 Métis chartered communities.

Three rapidly growing communities also included in Fraser Health are Abbotsford, Maple Ridge, and Surrey; all three are served by expanding community-focused acute-care hospitals and related services.

Fraser Health provides health care services for the following communities:

Services provided by Fraser Health include primary health care, community home care, mental health and addictions, acute medical, and surgical services.

Fraser Health has 13 acute-care hospitals including 3 regional hospitals and 9 community hospitals as well as an outpatient care and surgery centre.
