Basildon and Thurrock University Hospitals NHS Foundation Trust

Basildon and Thurrock University Hospitals NHS Foundation Trust provided healthcare for people in south west Essex, in the East of England. There were two hospitals in the trust, a specialist cardiothoracic centre and one clinical centre: Basildon University Hospital, Orsett Hospital, The Essex Cardiothoracic Centre and Billericay St. Andrew's Centre. It became a Foundation Trust in 2004.

A merger with Southend University Hospital NHS Foundation Trust and Mid Essex Hospital Services NHS Trust was proposed in January 2018. On 31 July 2019 the Secretary of State for Health and Social Care endorsed the merger and a provisional date of 1 April 2020 was agreed.
