Thomas Gambier Parry, J.P., D.L., was a British artist and art collector. He is best remembered for his development of the Gambier Parry process of fresco painting, and for forming the significant collection of early Italian paintings and objects that his heirs gave to the Courtauld Institute of Art in London, where many are displayed in the Courtauld Gallery.

The Courtauld Gallery is an art museum in Somerset House, on the Strand in central London. It houses the collection of the Samuel Courtauld Trust and operates as an integral part of the Courtauld Institute of Art.
