Francis Henry Underwood (January 12, 1825 – August 7, 1894) was an American editor and writer.

He was the founder and first associate editor of The Atlantic Monthly in 1857 while still working as a publisher's assistant.

[1] Underwood worked in Kentucky from 1845 to 1850, but his hatred of slavery caused him to quit the state.

Originally, he planned to launch a Free-soil magazine in 1853, but the idea did not come to fruition until The Atlantic Monthly in 1857.

[2] Underwood traveled to Britain in August 1885 on SS Cephalonia.
