Erasmus Darwin Shattuck was an American politician and judge in the state of Oregon. He served as the 7th Chief Justice of the Oregon Supreme Court serving from 1866 to 1867. He served two separate terms on the Oregon's high court, was a district attorney, and a member of the Oregon Constitutional Convention in 1857.

The Oregon Constitutional Convention in 1857 drafted the Oregon Constitution in preparation for the Oregon Territory to become a U.S. state. Held from mid-August through September, 60 men met in Salem, Oregon, and created the foundation for Oregon's law. The proposal passed with a vote of 35 for adoption to 10 against. Oregon then became the 33rd state of the Union on February 14, 1859.
