Sir George Robert Laking KCMG (15 October 1912 – 10 January 2008) was a New Zealand diplomat who served as High Commissioner to the United Kingdom, Ambassador to the United States, Secretary of Foreign Affairs and Chief Ombudsman.

In 1940, Laking became head of the Organisation for National Security, managing the War Cabinet Secretariat, a post he held until 1948.

In 1949, Laking was appointed Minister to the New Zealand Embassy in Washington, serving as deputy to Ambassador Carl Berendsen, for seven years.

During this time, Laking was frequently the main point of contact between New Zealand and the US administration, owing to Berendsen's substantial involvement in the establishment of the United Nations as Permanent Representative to that organisation.

In 1967, Laking returned to Wellington where he succeeded McIntosh in the posts of Secretary of Foreign Affairs and as head of the Prime Minister's Department.
