Charles Barry Jr. (1823–1900) was an English architect of the mid-late 19th century, and eldest son of Sir Charles Barry. Like his younger brother and fellow architect Edward Middleton Barry, Charles Jr. designed numerous buildings in London. He is particularly associated with works in the south London suburb of Dulwich.
