Amir Khan's new promotional company has made the boxer's younger brother its first signing.
Haroon Khan will now be looked after by Super Fight Promotions.
Haroon told Sky Sports News: "I've always wanted to turn professional and to do so under Super Fight Promotions was an opportunity that I couldn't turn down.
"I have big ambitions but will take things a step at a time and I know I've got the best team behind me, who have that experience, to help guide my career to the very top."
The 21-year-old took bronze at the 2010 Commonwealth Games in Delhi in the flyweight class.
