Christopher Columbus Andrews (October 27, 1829 – September 21, 1922) was an American soldier, diplomat, newspaperman, author, and forester.

He passed his bar examination two years later and established a law practice in Newton, Massachusetts, where he served as a member of the city school board in 1851–1852.

In July 1863, Andrews was promoted to colonel and commanded a brigade in the operations to capture Little Rock, Arkansas, later in the year.

Andrews was assigned to the command of the Second Division of the XIII Corps, and participated in the siege and storming of Fort Blakeley in Alabama.

Andrews was appointed by President Grant as United States Minister to Denmark on April 16, 1869, and was sworn into office but never proceeded to his post.
