Rock & Republic is an American jeans brand founded by fashion mogul Michael Ball in 2002. Good friend Andrea Bernholtz serves as the company president. Prior to starting the company, Ball was an avid cyclist who gained design experience by creating his cycling team uniforms. Rock & Republic is well known for "VB Rocks", a line of "bum"-flattering jeans and casual wear designed by singer Victoria Beckham.

Although best known for its high-end denim wear, Rock & Republic features clothing lines for men, women and children, including maternity wear, shoes and recent introductions of eye wear, handbags and cosmetics.

Rock & Republic merchandise is carried in Bergdorf Goodman, Bloomingdale, Harrods, Harvey Nichols, Holt Renfrew, Lord & Taylor, Neiman Marcus, Nordstrom, Saks Fifth Avenue, and Von Maur, as well as small boutiques, such as Len Druskin and Stanley Korshak. There are currently two freestanding Rock & Republic retail boutiques at the Wynn in Las Vegas and on Robertson Boulevard in Los Angeles.

The company sponsors a professional cycling team named Rock Racing, which is noted for its constantly changing team kit as well as its Cadillac Escalade team car.
