Oldchurch Hospital was a hospital in London, United Kingdom, located in Romford, in the London Borough of Havering and part of the Barking, Havering and Redbridge Hospitals NHS Trust.
The hospital incorporated the buildings of the former Romford Union Workhouse, built in 1838. The poor law union covered Barking, Cranham, Dagenham, Great Ilford, Great Warley, Havering-atte-Bower, Hornchurch, Rainham, Romford, Upminster and Wennington. In 1930 the poor law union was abolished and it became the Oldchurch County Hospital. In 1948 it became part of the National Health Service.
