William Acton (1813–1875)) was a nineteenth century English physician and author from Dorset.

Acton was influenced by French physician Claude François Lallemand, who recommended circumcision to prevent spermatorrhea (excessive, involuntary ejaculation), which was then believed to be a disease.

Acton later devoted his efforts to the suppression of child masturbation, which was then thought to produce blindness and other disorders.
