Frank William Abagnale Jr. is an American security consultant, author, and convicted felon who committed frauds that mainly targeted individuals and small businesses. He later gained notoriety in the late 1970s by claiming a diverse range of workplace frauds, many of which have since been placed in doubt. In 1980, Abagnale co-wrote his autobiography, Catch Me If You Can, which built a narrative around these claimed frauds. The book inspired the film of the same name directed by Steven Spielberg in 2002, in which Abagnale was portrayed by Leonardo DiCaprio. He has also written four other books. Abagnale runs Abagnale and Associates, a consulting firm.

Catch Me If You Can is a semi-autobiographical book about criminal exploits allegedly engaged in by Frank Abagnale Jr., an American onetime con artist. Abagnale claims that, as a young man, he cashed $2.5 million worth of bad checks while impersonating a Pan Am pilot, a doctor, a teacher, and an attorney. The book is acknowledged to have been partly fictionalized, and the factual basis for the events contained in the book has been challenged. Co-written by Abagnale and Stan Redding, Catch Me If You Can was adapted into a film of the same name by director Steven Spielberg in 2002. In the film, Abagnale was portrayed by actor Leonardo DiCaprio.
