James Alfred Wanklyn (18 February 1834 – 19 July 1906) was a nineteenth-century English analytical chemist who is remembered today chiefly for his "ammonia method" of determining water quality and for his fierce arguments with those, such as Edward Frankland, who opposed him over matters related to water analysis.

He worked with Edward Frankland and Lyon Playfair.

He gives his name to the Wanklyn reaction.
