James Braddock Jr. is a fictional character appearing in American comic book published by Marvel Comics. The elder brother of the twin superheroes Brian and Betsy Braddock, he is a mutant possessing the ability to manipulate reality in a variety of ways. Though his mutant powers are very powerful, he is limited in that he is also a schizophrenic who believes reality to be his own dream. Originally a supporting character in his brother's solo comic book series, the emergence of his superhuman powers and subsequent mental illness have led him to become a super-villain associated with both Captain Britain and various X-Men comics.

Jamie Braddock first appeared in the UK title Captain Britain Weekly #9 (Dec. 1976), and was created by Chris Claremont, Herb Trimpe, and Fred Kida.

Jamie is the oldest son of Dr. James and Elisabeth Braddock. Nearly a decade older than his siblings, the twins Brian and Elisabeth ("Betsy"), Jamie had a relatively isolated childhood.

He made his name as a financial genius and was also a successful race car driver. He headed Braddock Industries, a company that flourished under his leadership. Eventually, Jamie discovered his brother's secret identity as Captain Britain and assisted him on several occasions. In his spare time, however, Jamie started to make illegal bets and his debts grew. Soon he became involved with various illegal activities in order to pay his debts. Starting out with minor crimes, Jamie eventually became involved with robbery, murder, and slave-trading in Africa, resulting in him being kidnapped by Doctor Crocodile, an African scientist (also a former R.C.X. agent). He forced Jamie to contact his brother, thinking that Brian was involved with Jamie's crimes as well. Crocodile's witch-doctor created a hallucination for Brian so that she and Crocodile could observe Brian's reaction to the crimes Jamie had committed. Convinced that Brian was innocent, Crocodile told Brian the truth about his brother's actions. Shocked and furious, Brian abandoned Jamie to his fate.
