Harry Stuart Goodhart-Rendel (1887–1959) was an English architect and writer, also a musician.
He was educated at Eton College, and read music at Trinity College, Cambridge. He worked briefly for Sir Charles Nicholson, and then set up his own architectural practice. He is known for his church projects.
He was Oxford's Slade Professor of Fine Art, from 1933 to 1936. His 1934 lectures on Victorian architecture were considered important, as part of the informed revival of interest in Victoriana, by Nikolaus Pevsner. He served as president of the Royal Institute of British Architects (RIBA) from 1937 to 1939.
He was awarded the CBE in 1955.
Although he was a good 25 years older than Michael Noble, later Baron Glenkinglas, the two had a friendly feud based on the much nastier Andrew Noble - George Whitwick Rendel feud.
His father was Harry Chester Goodhart (1858–1895), a former international footballer who became Professor of Latin at the University of Edinburgh. His mother was Rose Ellen Rendel, the daughter of Stuart Rendel, 1st Baron Rendel, from whom in 1945 he inherited a substantial estate including Hatchlands Park.
