Ainsworth is English in Origin.

Of English origin, Ainsworth is a transferred surname taken from the Lancashire locality near Bolton. The name stems from Old English worth, meaning fenced enclosure or homestead, attached to a personal name - likely Ægen/Agne - so the sense is “enclosure belonging to Ægen.” Medieval records show spellings such as Aynesworth and Ainesworth, reflecting Middle English orthography.

As a surname, it’s documented from the early 13th century, borne by families in northwestern England; one notable bearer is the Victorian novelist William Harrison Ainsworth. As a given name, Ainsworth emerged in the late 19th and early 20th centuries in Britain and the United States, part of the surname-as-first-name trend. Usage remains uncommon and leans masculine, though modern parents may treat it as unisex. Variant spellings include Aynsworth, Aynesworth, and the rare Ainsworthe; short forms such as Ains or Worth appear in casual use.
