PeaceHealth is a not-for-profit health care system that owns and operates ten hospitals and numerous clinics in the U.S. states of Alaska, Oregon, and Washington.

The organization is headquartered in Vancouver, Washington, and was founded by the Catholic Sisters of St. Joseph of Peace in 1976.

[4][5] After continued growth, the Sisters consolidated their healthcare ministries in the west and formed a not-for-profit health care system in 1976,[4] and in 1994 the name was changed to PeaceHealth.

[6][7] Their partnership has continued until at least 2015,[needs update] when in October of that year, they jointly signed a letter of intent to collaborate on a health center in Vancouver, Washington.

[11] At the time, PeaceHealth had annual revenues of approximately $1.3 billion and operated seven hospitals.
