Leonard Shuffrey (31 March 1852 – 27 December 1926) was a British architect and architectural designer of the late Victorian and Edwardian period. He was a leading figure of the aesthetic movement that had a significant impact on the development of buildings and their interiors and their settings, both across London and the South of England. Noted for his wallpaper, fireplaces and ornate plasterwork, Shuffrey was thought the equal of William Morris in his creativity and skill as a craftsman. His output is often found in decorative schemes with William Morris, Edward Ould, William De Morgan, and other preeminent Arts & Crafts and late Pre-Raphaelite decorative artists of the day.

Leonard Atkinson Shuffrey was born on 31 March 1852 in Wood Green, Witney, Oxfordshire, into an old Wood Green family of blanket weavers and tanners of Huguenot origin, who had lived at 7 Narrow Hill since the early eighteenth century. His parents were Samuel Shuffrey (1810–1889) and Sarah Shuffrey, née Baylis (1819–1875). One of seven siblings, Shuffrey was the elder brother of the celebrated watercolour artist James Allen Shuffrey. Their cousin was the Revd William Shuffrey (1851–1932), who was Vicar of Arncliffe and Honorary Canon of Ripon Cathedral. Leonard Shuffrey attended Bloxham School between 1856 and 1867.

Shuffrey's first marriage, in 1873, was to Sarah Fletcher, a relative of Banister Fletcher (senior), with whom he had a son, also named Leonard. Leonard senior's second wife, whom he married in 1877 after the death of Sarah, was Martha Carey, great-granddaughter of James Hardy, relative of Admiral Sir Thomas Hardy, Captain of the Victory. Leonard and Martha had two sons, Gilbert (born 1891) and Paul Shuffrey (born 1889), and a daughter, Kathleen (b. 1899). All of Shuffrey's sons attended St Paul's School, London.

Leonard Shuffrey worked briefly for Carron's ironworks, before becoming articled to the architect Banister Fletcher (senior) in London. In 1871, after several years of architectural experience, he became an early member of the Architectural Association, where he was an associate of Aston Webb. This was the start of a long collaboration with Aston Webb, with Shuffrey providing numerous interior fittings for Webb's buildings, including at Christ's Hospital, Horsham (1902), his Birmingham University Buildings, (1909). and for Webb's Malvern College War Memorial Library (1925).

Shuffrey was, above all things, a superlative craftsman. Early in his career he developed an intense interest in decorative design, and appears to have focused on, and made a name for himself in, this area of work.

In 1880, with the help of a sleeping partner, George Campbell Sherrin, Shuffrey founded his practice, Shuffrey & Co., with the aim of supplying fireplaces, wallpaper, tiles, and later, decorative plasterwork. The firm, had premises at 38–39 New Cavendish Street in London. Shuffrey & Co's work can be found across London and the South of England – particularly in London, and his home county of Oxfordshire. The firm had a woodworking factory, managed by Shuffrey's son Leonard, for making the overmantles and fireplaces, near to the Shuffrey's family's home in Wood Green, Witney.

In 1880, Shuffrey won a competition run by The British Architect magazine to design a terracotta fireplace. The award was presented by the architect Alfred Waterhouse, who noted that Shuffrey was already well established in this field. Shuffrey was later to provide fireplaces for Waterhouse's Pearl Life Assurance Building in Liverpool (1896–1898).

Shuffrey & Co. sought business through advertising in journals and magazines, and by exhibiting at trade events. In 1882, the firm had a stand at the Fine Art & Industrial Exhibition at St James' Hall in Manchester, where their display included mantels, fireplaces, paperhangings and door furniture.
