Daniel Brett Weiss (born April 23, 1971) is an American television writer, director, and producer. Along with his collaborator David Benioff, he is best-known as co-creator of "Game of Thrones" (2011–2019), the HBO adaptation of George R. R. Martin's series of books "A Song of Ice and Fire".

On July 19, 2017, Weiss announced that he and Benioff were going to begin production on another HBO series, "Confederate", after the final season of "Game of Thrones". Weiss and Benioff said, "We have discussed Confederate for years, originally as a concept for a feature film, but our experience on Thrones has convinced us that no one provides a bigger, better storytelling canvas than HBO."

On February 6, 2018, Disney announced that Weiss and Benioff would write and produce a new series of "Star Wars" films after the last season of "Game of Thrones" ended in 2019. Toward the end of the last season, a petition to HBO was started on Change.org. It described showrunners Benioff and Weiss as "woefully incompetent writers" and demanded "competent writers" to remake the eighth season of "Game of Thrones" in a manner "that makes sense". The petition eventually amassed over 1.5 million signatures. In the Chicago Sun Times, Richard Roeper wrote that the backlash to the eighth season was so great that he doubted he had "ever seen the level of fan (and to a lesser degree, critical) vitriol leveled at" Game of Thrones.
