William Edward Ayrton, FRS (14 September 1847 – 8 November 1908) was an English physicist and electrical engineer.

Ayrton was born in London, the son of Edward Nugent Ayrton, a barrister, and educated at University College School and University College, London. He later studied under Lord Kelvin at Glasgow.

Ayrton’s second wife, Hertha Marks Ayrton, whom he married in 1885, assisted him in his research, and became known for her own scientific work on the electric arc and other subjects. In 1899, Ayrton supported Hertha on her way to being elected the first woman member of the Institution of Electrical Engineers and the Royal Society awarded her a Royal Medal in 1906. Their daughter Barbara later became a Labour MP, and grandson Michael Ayrton, was an artist and sculptor.

Previously, Ayrton had been married to a cousin, Matilda Chaplin (1846–1883); their marriage had taken place while Ayrton was on home leave from India and Matilda was involved in the Edinburgh Seven campaign to open medical education to women.

Chaplin and Ayrton's daughter was the feminist and author Edith Ayrton, wife of Israel Zangwill and mother of Oliver Zangwill.
