Samuel Post Davis (April 4, 1850 – March 17, 1918) was an American journalist, politician, and historian.
Although primarily a journalist, Davis also wrote poetry, plays, short stories, and humorous sketches.
With his Episcopalian priest father, Davis moved to New Jersey, and Wisconsin.
In 1879, after the death of Henry Rust Mighels, owner and editor of the Carson City Nevada Appeal, his widow, Nellie Verrill Mighels Davis, became the publisher, and shortly thereafter, hired Sam Davis as her editor.
She married Davis the next year, and he took over operations of the Nevada Appeal.
