"Fifty Grand" is a short story by Ernest Hemingway. It was first published in The Atlantic Monthly in 1927, and it appeared later that year in Hemingway's short story collection Men Without Women.
"Fifty Grand" tells the story of Jack Brennan as he trains for and boxes in his fight with challenger Jimmy Walcott. The first part of the story takes place in New Jersey, the second in New York City. It shows Hemingway's love for and knowledge of boxing, and his use of omission and understatement.
