Daniel Mendoza (5 July 1765 – 3 September 1836) was an English boxer, who was a popular prizefighter in late 18th-century Britain. He played a significant role in advancing the scientific technique in boxing by publishing two books on the subject (The Art of Boxing and The Modern Art of Boxing) and by conducting frequent public exhibitions.
While modern sources often portray Mendoza as the English Prizefighting Champion from 1792 to 1795, contemporary sources from the late 18th and early 19th century do not describe Mendoza in this manner.
