Isaac Hill (April 6, 1788 – March 22, 1851) was an American politician, journalist, political commentator and newspaper editor who was a United States senator and the 16th governor of New Hampshire, serving two consecutive terms.

Hill was born on April 6, 1788, in West Cambridge, Massachusetts, (now Belmont).

The brothers-in-law had a difficult relationship due to their political differences, and Moore later worked for the competing New Hampshire Journal.

He resigned from the Senate when he was elected Governor of New Hampshire, serving 1836–1839, and chose not to run for re-election.

He died on March 22, 1851, in Washington, D.C.,[3][4][5] and was buried at Blossom Hill Cemetery in Concord, New Hampshire.
