Sir John Oliver Wright GCMG GCVO DSC (6 March 1922 – 1 September 2009) was a British diplomat.

He was the younger son of Arthur Wright, a catering manager and hotelier, and his wife, Ethel Louisa Hicks, (née Shearod).

In 1941, having completed his university degree, Wright joined the Royal Naval Volunteer Reserve.

He would have become the new Master in 1982, but was recalled to the Diplomatic Service to become British Ambassador to the United States and therefore never took up the appointment.

He was appointed GCVO following the state visit undertaken by Queen Elizabeth II to West Germany between 22 and 26 May 1978.
