David Rambo (born 1955) is a writer, actor and producer.

He grew up in Spring City, Pennsylvania. His grandmother and mother were librarians which helped develop his lifelong interest in literature and art.

After moving to Los Angeles to become an actor, Rambo started working in the real estate business. He would afterwards begin a career on theatre, first acting and then writing and adapting plays.

In 2004 he wrote his first script for a television show, an episode for the American crime drama CSI: Crime Scene Investigation entitled Butterflied. Butterflied aired on January of that year and it was the highest rated TV program of the week. Rambo would then join the CSI writing team, creating episodes like Who Shot Sherlock?, Kiss-Kiss, Bye-Bye and Still Life. He is now a supervising producer of the show. In 2006, Rambo wrote "The Lady With All the Answers", a play about the life and work of "Eppie" Lederer, better known as Ann Landers. The play has been widely produced across the country. An off-Broadway production starring Judith Ivey opened October 14, 2009 at the Cherry Lane Theatre.

In May of 2011, Rambo visited Elsinore High School in Wildomar, California as a special guest speaker for the 2010 graduating class.

During summer of 2010, it was announced that Rambo would not be returning to 'CSI.' He would now work for the ABC revival of 'V.'
