The Old Man and the Sea is a 1952 novella by the American author Ernest Hemingway. Written between December 1950 and February 1951, it was the last major fictional work Hemingway published during his lifetime. It tells the story of Santiago, an aging fisherman, and his long struggle to catch a giant marlin. The novella was highly anticipated and was released to record sales; the initial critical reception was equally positive, but attitudes have varied significantly since then.

Hemingway began writing The Old Man and the Sea in Cuba during a tumultuous period in his life. His previous novel Across the River and Into the Trees had met with negative reviews and, amid a breakdown in relations with his wife Mary, he had fallen in love with his muse Adriana Ivancich. Having completed one book of a planned "sea trilogy", Hemingway began to write as an addendum a story about an old man and a marlin that had originally been told to him fifteen years earlier. He wrote up to a thousand words a day, completing the 26,531-word manuscript in six weeks.
