Steve Marshall (born July 19, 1943) is a writer and producer for film and television. He began his entertainment career in radio, rising to the level of Program Director of the CBS-owned KNX-FM in Los Angeles in the early 70's.

After a number of successful years in radio, Marshall wrote a script on spec for the CBS television series WKRP in Cincinnati. Not only did the producers of the show buy his spec script, but they put him on staff as well. During his three years with the series, he wrote many of its episodes and eventually teamed up with another WKRP writer, Dan Guntzelman. After the cancellation of the series, Marshall and Guntzelman executive produced the All in the Family spin-off, Gloria, with Sally Struthers and Burgess Meredith. The series aired on CBS during the 1982-83 season and was canceled, even though it was the 19th highest rated show of the season.

Marshall and his partner then created a short lived series for ABC titled Off the Rack, starring Edward Asner and Eileen Brennan, which only ran for seven episodes before being canceled. Under contract as writer/producers to Warner Bros. Television, the two were asked to take over the running of the studio's new series, Growing Pains. They kept the series in the Nielsen top 20 for most of its seven-year run, also creating a spin-off series for ABC, Just the Ten of Us. That series was canceled after two seasons, at which point Marshall and Guntzelman left Growing Pains in 1992 and went their separate ways.

A couple years later the two re-united to produce a series from a pilot they had written for NBC in 1984, a look at TV news titled Live Shot, which was given new life on the newly formed UPN network in 1995. That series was canceled after 13 episodes. During their partnership, Marshall and Guntzelman wrote a number of feature film scripts, including Revenge of the Nerds II: Nerds in Paradise, a 20th Century Fox release.

Steve Marshall is the current offensive line coach for the Cleveland Browns.
