Sir Osborne Arkell Smith, KCSI, KCIE (26 December 1876 – 30 August 1952) was the first Governor of the Reserve Bank of India, a post he held from 1 April 1935 to 30 June 1937.

Smith was a professional banker who served for 20 years with the Bank of New South Wales and 10 years with the Commonwealth Bank of Australia.

He was knighted in March 1929,[1] and was invested with his knighthood by the Governor-General of India, Lord Irwin, at the new Viceroy's House in New Delhi on 27 February 1930.

Since his outlook on policy issues like the exchange rates and interest rates differed with that of the Government, he resigned before the completion of his term of office.

Sir Osborne did not sign any Indian rupee notes during his tenure.
