Dualstar Entertainment Group, LLC is a privately held American limited liability company owned by twin sister actresses Mary-Kate Olsen and Ashley Olsen, which produced films, television series, magazines, video games, and other popular media.

The company Dualstar Productions was originally started in 1993 by Mary-Kate and Ashley Olsen, then-stars of Full House, at the age of 6.

Dissatisfied by the BMG deal, the Olsens opted to move the Dualstar Video label to WarnerVision Entertainment in 1995.

[11] In 2006, Dualstar partnered with Dylan and Cole Sprouse, the twin brothers from Disney's The Suite Life of Zack & Cody, to produce Code, a magazine geared toward a young male demographic.

A class action lawsuit against Dualstar alleges that the Entertainment Group failed to pay interns for menial tasks.
