Emily Post (née Price; c. October 27, 1872 – September 25, 1960) was an American author, novelist, and socialite, famous for writing about etiquette.

Post was born Emily Bruce Price in Baltimore, Maryland, possibly in October 1872. The precise date is unknown. Her father was the architect Bruce Price, famed for designing luxury communities. Her mother Josephine (Lee) Price of Wilkes-Barre, Pennsylvania was the daughter of a wealthy coal baron. After being educated at home in her early years, Price attended Miss Graham's finishing school in New York after her family moved there.

Post began to write once her two sons were old enough to attend boarding school. Her early work included humorous travel books, newspaper articles on architecture and interior design, and magazine serials for Harper's, Scribner's, and The Century. She wrote five novels: Flight of a Moth (1904), Purple and Fine Linen (1905), Woven in the Tapestry (1908), The Title Market (1909), and The Eagle's Feather (1910). In 1916, she published By Motor to the Golden Gate—a recount of a road trip she made from New York to San Francisco with her son Edwin and another companion.

Post wrote her first etiquette book Etiquette in Society, in Business, in Politics, and at Home (1922, frequently referenced as Etiquette) when she was 50. It became a best-seller with numerous editions over the following decades. After 1931, Post spoke on radio programs and wrote a column on good taste for the Bell Syndicate. The column appeared daily in over 200 newspapers after 1932.
