John Randolph Webb (April 2, 1920 – December 23, 1982) was an American actor, television producer, director, and screenwriter, most famous for his role as Joe Friday in the Dragnet franchise, which he created. He was also the founder of his own production company, Mark VII Limited.

Webb started his career in the 1940s as a radio personality, starring in several radio shows and dramas—including Dragnet, which he created in 1949—before shifting to acting in the 1950s, creating television adaptations of Dragnet for NBC. Throughout the 1960s, Webb worked in both acting and television production, creating Adam-12 in 1968, and in 1970, Webb retired from acting to focus on producing, creating Emergency! in 1972. Webb continued to make television series, and although many of them were less successful and short-lived, he wished to rekindle his prior successes, and had plans to return to acting in a Dragnet revival before he died.

Webb's production style aimed for significant levels of detail and accuracy. Many of his works focused on law enforcement and emergency services in the Los Angeles area, most prominently the Los Angeles Police Department (LAPD), which directly supported the production of Dragnet and Adam-12. A staunch conservative, Webb often used his works to voice his opinions on political and social issues, evident in the speeches he would embed into Dragnet's scripts.
