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.

The Royal Institute of British Architects (RIBA) is a professional body for architects primarily in the United Kingdom, but also internationally, founded for the advancement of architecture under its royal charter granted in 1837, three supplemental charters and a new charter granted in 1971.
