Osment is a surname of English origin, predominantly found in the southern counties of England, with a significant presence in the United States and Canada.

The name is derived from the Old English personal names Osmaer or Osmund, which combine the elements oss or os meaning "god" with a second element such as maer ("fame") or mund ("protection"). As a result, the surname can be interpreted as "god‑fame" or "divine protection". The suffix -ment is believed to have been added later, forming the patronymic surname Osment, implying "the son of Osmaer" or "the son of Osmund".

Variant spellings include Osman, Osmant, Osmint, Osmer, Usmar, Ozment, Ozman, Ozement, and the more widely recognisable Osborne and Osbourne. These variations arose from the absence of standardised spelling in early English records.

The earliest documented usage of the name appears in the Pipe Rolls of Devonshire in 1230, where a William Osmere is recorded. Earlier, the personal names Osmar and Osmer are mentioned in the Domesday Book of 1086 for Leicestershire and Devonshire respectively, but the surname itself does not appear until the early 13th century.

Church registers provide further evidence of the surname’s continuity: a marriage between Fanny Osment and William Batcheler took place on 25 July 1779 at St. Martin in the Fields, Westminster; the christening of Caroline Osment, daughter of John and Esther Osment, on 18 May 1823; and the christening of Ann Charlotte Osment on 22 July 1848 at St. Pancras' Old Church. These records confirm the surname’s presence in London throughout the 18th and 19th centuries.

In the United States, the surname is most common in Maryland, Tennessee and California, with a large concentration in Los Angeles County. According to the 2019 United States Census, the name ranked 2,604th in prevalence, with 5,263 bearers recorded. The same census notes 2,114 individuals with the surname in Canada. The name is relatively rare in the United Kingdom, where it is found mainly in the counties of Somerset, Devon, Sussex, Dorset and Berkshire.

Although further migration has spread the surname to other English-speaking countries, the core of the Osment lineage remains rooted in England, with historical ties that can be traced back to the Anglo‑Saxon period. The surname’s meaning, derived from Old English components, reflects a tradition of associating personal names with divine protection or fame.
