John Charles Layfield, Bradshaw, or still John Bradshaw Layfield (JBL) is a former American professional wrestler and entrepreneur signed to WWE.
Prior to pursuing a career in professional wrestling, John Layfield was an American football player for Abilene Christian University, where he played offensive tackle and played in the Lone Star Conference as a junior and senior. He later signed with the Los Angeles Raiders, but was released by the franchise before the 1990 season and then moved on to the San Antonio Riders.

Layfield began his professional wrestling career in the early 1990s, wrestling under the ring name Blackjack Bradshaw for various American independent promotions. In January 1996, he signed a contract with the World Wrestling Federation; during this time he tag teamed with Ron Simmons, with whom he soon after formed the Acolytes Protection Agency. Following Simmons' retirement in March 2004, Layfield took on the guise of a wealthy Texan businessman and began calling himself John Bradshaw Layfield.

In WWF/E he won the WWE Championship once, the Intercontinental Championship once, the United States Championship once, the European Championship once, the Hardcore Championship eighteen times and the World Tag Team Championship three times, resulting in being the tenth wrestler in history to complete the Grand Slam. In 2021 he was inducted into the WWE Hall of Fame.

He is a regular guest on The Cost of Freedom on the US Fox News Channel and has previously appeared on several CNBC shows. He has also written a best-selling book on financial planning entitled Have More Money Now. In February 2005, he married his second wife Meredith Whitney in Key West, Florida.
