Harper's Magazine (also called Harper's) is a monthly magazine of literature, politics, culture, finance, and the arts, with a generally liberal perspective. It is the second-oldest continuously published monthly magazine in the U.S. (Scientific American is the oldest). The current editor is Ellen Rosenbush, who replaced Roger Hodge in January 2010. Harper's Magazine has won many National Magazine Awards.

Harper's Magazine was launched as Harper's New Monthly Magazine in June 1850, by the New York City publisher Harper & Brothers; who also founded Harper's Bazaar magazine, later growing to become HarperCollins Publishing. The first press run, of 7,500 copies, sold out almost immediately; circulation was some 50,000 issues six months later.

The early issues reprinted material already published in England, but the magazine soon was publishing the work of American artists and writers, and in time commentary by the likes of Winston Churchill and Woodrow Wilson. The first appearance in print of portions of Moby Dick occurred in Harper's Magazine in Oct. 1851 under the title, "The Town-Ho's Story".

Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), better known by his pen name Mark Twain, was an American author and humorist. He is most noted for his novels, The Adventures of Tom Sawyer (1876), and its sequel, Adventures of Huckleberry Finn (1885), the latter often called "the Great American Novel."

Twain grew up in Hannibal, Missouri, which would later provide the setting for Huckleberry Finn and Tom Sawyer. He apprenticed with a printer. He also worked as a typesetter and contributed articles to his older brother Orion's newspaper. After toiling as a printer in various cities, he became a master riverboat pilot on the Mississippi River, before heading west to join Orion. He was a failure at gold mining, so he next turned to journalism. While a reporter, he wrote a humorous story, "The Celebrated Jumping Frog of Calaveras County", which became very popular and brought nationwide attention. His travelogues were also well-received. Twain had found his calling.

He achieved great success as a writer and public speaker. His wit and satire earned praise from critics and peers, and he was a friend to presidents, artists, industrialists, and European royalty.
