Moorfields Eye Hospital is a specialist National Health Service (NHS) eye hospital in Finsbury in the London Borough of Islington in London, England run by Moorfields Eye Hospital NHS Foundation Trust. Together with the UCL Institute of Ophthalmology, which is adjacent to the hospital, it is the oldest and largest centre for ophthalmic treatment, teaching and research in Europe.

Moorfields Eye Hospital was founded at Charterhouse Square in 1805 as the London Dispensary for curing diseases of the Eye and Ear, by John Cunningham Saunders, assisted by John Richard Farre. It moved to a site on the former Moorfields in 1822, before moving to its present site in 1899, and became part of the National Health Service in 1948. These anniversaries gave it the unique ability to celebrate a centenary in 1999 and a bicentenary in 2005.

The new Richard Desmond Children's Eye Centre (RDCEC), was endowed by the publisher, Richard Desmond, and was opened by Queen Elizabeth II in February 2007. Its location is adjacent to the hospital's main City Road building.

In December 2021, it was announced that the Moorfields building on City Road and adjacent building "Kemp House" had been sold to private developers, and that the hospital would relocate to a new facility near King's Cross railway station at the St Pancras Hospital site in Camden

Moorfields Eye Hospital is a major centre for postgraduate training of ophthalmologists, orthoptists, optometrists, and nurses. It has also played a pivotal role in ophthalmic research. Sir Stewart Duke-Elder founded the Institute of Ophthalmology, formerly the Central London Ophthalmic Hospital in Gray's Inn Road and (now an integral part of University College London), and Sir Harold Ridley, Charles Schepens, and Norman Ashton have carried out research at Moorfields and the Institute.

Founded in 1963, The Friends of Moorfields Charity is an independent registered charity, raising funds for the benefit of the patients of Moorfields Eye Hospital. The primary aim of this charity is to provide supplementary services and equipment for the comfort and well-being of Moorfields' patients and their visitors. It contributes towards buying much needed technical items for professional use in the hospital's clinics, satellite centres, operating theatres and research laboratories. The charity also promotes and manages a wide range of volunteers, supporting the work and service of the hospital.
