Emanuel Vincent Harris OBE RA (26 June 1876 – 1 August 1971), often known as E. Vincent Harris, was an English architect who designed several important public buildings in traditional styles.

He was born in Devonport, Devon, and educated at Kingsbridge Grammar School.

He was articled to the Plymouth architect James Harvey in 1893;[1] in 1897 he moved to London, where he assisted E. Keynes Purchase, Leonard Stokes and Sir William Emerson.

He was appointed an Officer of the Order of the British Empire (OBE) in the 1919 Birthday Honours.

He was primarily a classicist; A. Stuart Gray wrote: "Some of his buildings suggest the influence of Sir Edwin Lutyens, but are bolder, balder, and less subtle or more frank depending on one's point of view.
