William Wardroper M.R.C.S. L.S.A. (7 April 1804 – 26 June 1875) was a British homeopathic surgeon who was Medical Officer at the Brighton Homeopathic Dispensary, where he worked alongside Charles Cobbe and Henry Rider Madden. Wardoper subsequently practiced in Nottingham and, later, in Lower Norwood, Surrey.

William Wardoper was one of the signatories to a letter sent to the London Morning Post newspaper in March, 1845 that sought to distance British homeopathy from the dietetic treatment used by Dr. Paul Francois Curie in a case that had resulted in the death of the patient. The other homeopaths who signed the letter repudiating Curie’s methods were: Frederick Hervey Foster Quin, Hugh Cameron, John Darby Charles, J. Chapman, Alfred Day, John James Drysdale, Harris Dunsford, Thomas Engall, Joseph Gilioli, James Walter Goodshaw, William Hering, Claudius B. Ker, Charles Joseph Berry King, William Hamilton Kittoe, Henry Rider Madden, Victor Massol, William H. Mayne, George Newman, John Norton, Samuel Thomas Partridge, Edward Phillips, and Robert Walker.

William Wardroper was born in April 1804, in Midhurst, Sussex, the eldest son of solicitor Richard Wardroper (1775 – 1849) and Frances Catherine Cutfield (1775 – 1815).

In 1828, Wardroper was admitted as a Member of the Royal College of Surgeons. Two years later, in 1830, he received his Licence from the Worshipful Society of Apothecaries.

Wardroper set up in practice in London and in 1845 was at 45 Welbeck Street, Cavendish Square.

In September 1841, Wardoper married Louisa Marianne Hillyard (1820 – 1895) at Marylebone parish church. They had three sons: Licensed victualler Frederick William Ball Wardroper (1843 – 1884), actor Henry Sheehan Wardroper (1845 – 1910), and comedian Walter Hillyard Wardoper (1847 – 1908).

By the end of the decade Wardroper had moved out of London. In 1850, he was in Brighton, where he was Medical Officer at the Homeopathic Dispensary. After Brighton, in 1851, he was listed as practicing in Nottingham.

In 1860, Wardoper had relocated and was in Lower Norwood, Surrey.

Wardroper was sick for more than two decades, and died at Epsom, Surrey, on 26 June 1875, aged 71.
