John Henry Boyes CMG (6 March 1886 – 1 July 1958) was the fifth Public Service Commissioner in New Zealand.
He was chairman of the Social Security Commission, in between his terms as Public Service Commissioner (1936-38 & 1941–46).
In 1936 the Labour government would have preferred Boyes to Thomas Mark as Public Service Commissioner, so appointed Boyes and Mark as Joint Commissioners.
There was an awkward two years, before Boyes was appointed to establish the new Social Security Department.
