Daniel Peter Masterson (born March 13, 1976) is an American actor. He portrayed Steven Hyde in That '70s Show (1998–2006), Milo Foster in Men at Work (2012–2014), and Jameson "Rooster" Bennett in The Ranch (2016–2018). As of May 2023, he is also a convicted rapist.

In May 2023, Masterson was convicted of raping two women in 2003. A third count of rape resulted in a hung jury. In September 2023, he was sentenced to 30 years to life in prison. Masterson is a Scientologist, as were his victims at the time of the assaults. The Church of Scientology's attempts to silence the victims, and its subsequent interference, resulted in a 20-year delay in bringing the crimes to justice.
