Jack Thomas Watts (15 April 1909 – 10 August 1970) was a New Zealand politician of the National Party and the twenty-ninth Minister of Finance, from November 1954 to 12 December 1957, when he retired.

He was educated at Christchurch Boys High School and Canterbury University where he attained a Master of Laws.

He was medically discharged from the army in early 1943 due to high blood pressure.

Watts was bitterly disappointed feeling that he (who held a more prominent portfolio and had been in the House for three years longer) should have been chosen.

[8] After exiting politics he resumed his profession as a legal practitioner and was also a member of the board of directors of several commercial companies.
