Harold Owen Luder was a British architect who designed a number of notable and sometimes controversial buildings in the United Kingdom in the 1960s and 1970s, many now demolished. He served as chairman of the Architects Registration Board and twice as President of the Royal Institute of British Architects in 1981–1983 and 1995–1997. He established his own practice Owen Luder Partnership in 1957, and left in 1987 to form the consultancy Communication In Construction.

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.
