Stephen Wright Kellogg (b. Shelburne, Massachusetts, April 5, 1822 – d. Waterbury, Connecticut, January 27, 1904) was an American politician, attorney, military officer and judge. He worked on his father's farm until he was twenty, in the winter attending or teaching school. In the fall of 1842 he entered Amherst College, but remained there only two terms; then he joined the class of 1846 at Yale College, where he was a member of Skull and Bones and was graduated with highest honors. Among his classmates and fellow Bonesmen was the Hon. Henry Baldwin Harrison, his lifelong friend.
