Blackley (surname)

Blackley is a surname of English origin. It is a habitational name derived from a place name, most likely from one of the villages named Blackley in Lancashire and West Yorkshire, England. These place names are believed to be derived from the Old English words "blæc" meaning "black" or "dark" and "leah" meaning "wood," "clearing," or "meadow," thus describing a dark wood or clearing.

The surname Blackley has been recorded in England since the 13th century. As a surname, it is found primarily in England, but has spread to other English-speaking countries through migration and emigration, including the United States, Canada, Australia, and New Zealand.

Variations of the surname may include Blacklee, Blackly, and Blakely, although Blakely is often considered a distinct name with its own derivation.
