John Anthony Notte Jr. (May 3, 1909 – March 7, 1983) was an American politician, a Democrat, best known for serving as the 65th Governor of Rhode Island.

He later served as a member of staff of Senator Theodore F. Green from 1948 to 1956, and as Chairman of the North Providence Democratic town committee.

Under his administration, a family court was established and Rhode Island held its first one-day, one-place Democratic and Republican primaries.

He was defeated for re-election by Republican John Chafee in the state's tightest gubernatorial race ever – a margin of under 400 votes.

After he left office, he returned to his law practice and sought the Democratic nomination in the special election to the United States House of Representatives in 1967 but lost the primary.
