Harry Robson Lake (29 September 1911 – 21 February 1967) was a New Zealand politician who served as Minister of Finance for six years in the second National government in the 1960s.

He was then employed for five years at the Vacuum Oil Company before joining a firm of public accountants, in which he later became a partner.

Undoubtedly the reason for Lake's promotion was the fact he was a close friend and political confidante of Holyoake.

[5] In recognition of his lack of experience, however, Lake was officially ranked only sixth in Cabinet, a lower position than a minister of finance would normally expect.

In keeping with Holyoake's desire to maintain the status quo, Lake's tenure as minister of finance was relatively uneventful, with the primary focus being on stability.

In 1964, Lake suffered his first heart attack, which reduced his energy somewhat but did not impair his ability to perform his role.

[6] In February 1967 Lake returned to Christchurch to attend the funeral of his wife's uncle, where he suffered a second heart attack, and died.
