Isaac Reed (August 22, 1809 – September 19, 1887) was a United States representative from Maine.
[2] He was appointed as a member of the State board of agriculture and a trustee of the Maine Insane Hospital.
He was an unsuccessful candidate for election in 1850 to the Thirty-second Congress, but subsequently was elected as a Whig to the Thirty-second Congress to fill the vacancy caused by the death of Charles Andrews and served from June 25, 1852, to March 3, 1853.
In 1811 Reed's father purchased a house under construction begun in 1808 by the congregational reverend John R. Cutting.
