Robert Codman (December 30, 1859 - October 7, 1915) was bishop of the Episcopal Diocese of Maine, serving from 1900 to 1915.

He graduated from Harvard and practiced law for some years, but upon the death of his brother, the Reverend Archibald Codman, his thoughts turned to the ordained ministry.

As bishop he altered and expanded the cathedral by adding the Emmanuel chapel[4] which includes the Madonna and Child of John La Farge.

[10] During his later years, he was heavily involved in the Anti-Tuberculosis Society[11] and the Citizens’ Committee;[1] he saw both as working against the disadvantages of urban life.

Codman married Margarette B Porter in September 1915; he died three weeks later from a brain tumour.
