The hospital has its origins in the "Cheshire Lunatic Asylum" which opened on part of the site in 1829.
The name of the facility changed to "County Mental Hospital" in 1921, to the "Upton Mental Hospital" on joining the National Health Service in 1948, and then to the "Deva Hospital" in 1950.

By 1948, Chester Royal Infirmary specialized in surgery and out-patients and the City Hospital, Hoole, in chronic illnesses, chest, maternity, paediatric, and general medical cases.
Pre-war plans for the expansion of the Infirmary were eventually revived.
In 1963 a large out-patient and casualty department was opened at the infirmary; this was accompanied with the completion of the Chester inner ring road in 1967.
However, after the creation of the West Cheshire HMC (hospital management committee), a fresh decision was taken to focus all the hospital services for the district at a purpose-built site on Liverpool Road, adjacent to the county mental hospital facilities.

In 1968, the new site was renamed the "West Cheshire Hospital".
The maternity unit at the City Hospital was transferred to a new building at the south end of the site in 1971.
With the opening of a new general wing and A&E department in 1983, several surgical departments from the Royal Infirmary were relocated to the new buildings.
On 30 May 1984, West Cheshire Hospital was officially renamed the Countess of Chester Hospital by Prince Charles and Princess Diana.
In 1993, the Royal Infirmary site was closed after its remaining departments were transferred to the Countess.
The City Hospital, which had become a 120-bed geriatric unit, was closed in 1994 after its services were taken over by the Countess in 1991.

In January 2006, the CARE building, sometimes known as Outpatients Four, opened and started providing new facilities the Cardiac Catheter Laboratory, Department of Clinical Audiology, Renal & Urology Department and ENT Department.

In 2007, the Countess of Chester became the first hospital in the UK to completely ban smoking for both workers and patients.
In April 2014 a new two-storey wing was opened containing a state of the art 21 bed Intensive Care Unit on the first floor, replacing the old HDU and ITU wards.
On the ground floor is an expanded endoscopy unit and the bariatric outpatients department.
