The Big Fella: Babe Ruth and the World He Created is a non-fiction book by sportswriter Jane Leavy.

The book covers the life and career of Babe Ruth, focusing on his creation of modern celebrity culture and his high standing in the game of baseball long after his death.

It was nominated for the CASEY Award and won the Seymour Medal from the Society for American Baseball Research in 2019.

It also lays out how Ruth, with the help of his agent Christy Walsh, created his larger-than-life persona and became the first modern celebrity.

Much like her previous biographies, she structured around a three-week barnstorming tour Ruth underwent after his legendary 1927 season where he hit 60 home runs, along with his teammate Lou Gehrig.
