Samuel Nathaniel Cooke Jr. (26 June 1882 – 11 April 1964) was an English architect active in Birmingham, England in the early to mid 20th century. He was almost invariably credited as S. N. Cooke and his later work was carried out under the auspices of his firm S. N. Cooke and Partners. Works by him and the partnership include significant civic buildings, hospitals, and commercial premises in Birmingham and elsewhere in the United Kingdom.
