Osler is a surname of English origin, first recorded in the British Isles during the fifteenth and sixteenth centuries. It is associated with the Christian faith and has been borne by people who lived in England and spoke English.

The name derives in part from the Old English word osle or osel, meaning “blackbird.” In this sense it was a topographic or locational designation, given to a person who lived near land where blackbirds were common or in a place whose name reflected that bird. At the same time, research shows that the surname was introduced into England after the Conquest of 1066 from Old French, where it could have several occupational origins.

One possible derivation is from the Old French term hostelier, which in Middle English became hosteler. Originally it described the man in a monastery who took care of visitors, but over time it came to refer to the keeper of a commercial hostel, and is therefore an occupational surname for an innkeeper. An alternate French source is oiseleor or oiseleur, meaning a bird‑catcher or fowler, and oiselier, a seller of game or poulterer. In any case, the name is a job‑descriptive surname that later became hereditary.

The earliest surviving record of the name is Thomas Osselur in the Pipe Rolls of Yorkshire dated 1170, during the reign of King Henry I, who was known as the Builder of Churches. Other early attestations include Edid le Osteler as a witness in the Assize Court Rolls of Staffordshire in 1204, and Alberic le Oselur in the Feet of Fines in Cambridgeshire in 1208. Parish records from London give further evidence, such as the marriage of Ann Osler to John Whighthed on October 23rd 1586 at Allhallows, Honey Lane, and the christening of Thomas, son of Thomas Osler, on March 31st 1639 at St. Margaret's, Westminster.

Variant spellings of the surname are frequent, reflecting regional pronunciation and the lack of standardised spelling in medieval England. These include Oslar, Ossler, Oslor, Ostler, Horsler, Hustler, and Hosler. The diversity of forms illustrates how a single family name could evolve across centuries and localities while still retaining its core identity.
