Davis was born on April 18, 1864 in Philadelphia, Pennsylvania.
His mother Rebecca Harding Davis was a prominent writer in her day.
His father, Lemuel Clarke Davis, was himself a journalist and edited the Philadelphia Public Ledger.
As a young man, Davis attended the Episcopal Academy.
In 1882, after an unhappy year at Swarthmore College, Davis transferred to Lehigh University, where his uncle, H. Wilson Harding, was a professor.
While at Lehigh, Davis published his first book, The Adventures of My Freshman (1884), a collection of short stories.
Many of the stories had originally appeared in the student magazine the Lehigh Burr.
In 1885, Davis transferred to Johns Hopkins University.

After college, his father helped him gain his first position as a journalist at the Philadelphia Record, but he was soon dismissed.
After another brief position at the Philadelphia Press, Davis accepted a better-paying position at the New York Evening Sun where he gained attention for his flamboyant style and his writing on controversial subjects such as abortion, suicide and execution.
He first attracted attention in May to June 1889, by reporting on the devastation of Johnstown, Pennsylvania, following the destructive flood.
He added to his reputation by reporting on other noteworthy events such as the first electrocution of a criminal (the execution of William Kemmler in 1890).

Davis became a managing editor of Harper's Weekly, and was one of the world's leading war correspondents at the time of the Second Boer War in South Africa.
As an American, he had the opportunity to see the war first-hand from both the British and Boer perspectives.
Davis also worked as a reporter for the New York Herald, The Times, and Scribner's Magazine.

He was popular among a number of leading writers of his time, and is considered the model for illustrator Charles Dana Gibson's dashing "Gibson man", the male equivalent of his famous Gibson Girl.
He is mentioned early in Sinclair Lewis' book Dodsworth as the example of an exciting, adventure-seeking legitimate hero.

Davis had success with his 1897 novel Soldiers of Fortune, which he turned into a play written by Augustus Thomas.
His novel was filmed twice, in 1914 and in 1919 by Allan Dwan.
The 1914 version starring Dustin Farnum was shot on the Cuban locations that Davis used in his novel, and Davis was present during the filming.

During the Spanish–American War, Davis was on a United States Navy warship when he witnessed the shelling of Matanzas, Cuba, a part of the Battle of Santiago de Cuba.
His story made headlines, but as a result, the Navy prohibited reporters from being aboard any American naval vessel for the rest of the war.

Davis was a good friend of Theodore Roosevelt, and he helped create the legend surrounding the Rough Riders, of which he was made an honorary member.
Some have even gone so far to accuse Davis of involvement in William Randolph Hearst's alleged plot to have started the war between Spain and the United States in order to boost newspaper sales; however, Davis refused to work for Hearst after a dispute over fictionalizing one of his articles.

Despite his alleged association with yellow journalism, his writings of life and travel in Central America, the Caribbean, Rhodesia and South Africa during the Second Boer War were widely published.
He was one of many war correspondents who covered the Russo-Japanese War from the perspective of the Japanese forces.

Davis later reported on the Salonika Front of the First World War, where he was arrested by the Germans as a spy, but released.
