The Clapton Nursery also known as Mackay's Clapton Nursery and later Low's Clapton Nursery was a plant nursery established in the early 19th century by John Bain Mackay in Upper Clapton, London, and noted for its introductions of Australian and South American plants into cultivation. The nursery corresponded with Sir William Hooker and supplied the Royal Botanic Gardens, Kew with seed and cuttings.
