Robert Jay Rafelson (February 21, 1933 – July 23, 2022) was an American film director, writer and producer. He is regarded as one of the key figures in the founding of the New Hollywood movement of the 1970s. Among his best-known films as a director include those made as part of the company he co-founded, Raybert/BBS Productions, Five Easy Pieces (1970) and The King of Marvin Gardens (1972) as well as acclaimed later films, The Postman Always Rings Twice (1981) and Mountains of the Moon (1990). Other films he produced as part of BBS include two of the most significant films of the era, Easy Rider (1969) and The Last Picture Show (1971). Easy Rider, Five Easy Pieces and The Last Picture Show were all chosen for inclusion in the Library of Congress' National Film Registry. He was also one of the creators of the pop group and TV series The Monkees with BBS partner Bert Schneider. His first wife was the production designer Toby Carr Rafelson.

Robert Jay Rafelson was born in Manhattan on February 21, 1933 to a Jewish family, the son of Marjorie (Blumenfeld) and Sydney Rafelson, a hat ribbon manufacturer. His much-older first cousin, once removed, was screenwriter and playwright Samson Raphaelson, the author of The Jazz Singer, who wrote nine films for director Ernst Lubitsch. "Samson took an interest in my work," Rafelson told critic David Thomson. "If he liked a picture, then I was his favorite nephew. But if he didn't like it, I was a distant cousin!"

Rafelson attended the Trinity-Pawling School, a boarding school in Pawling, New York, from which he graduated in 1950. As a teenager he would often run away from home to pursue an adventurous lifestyle, including riding in a rodeo in Arizona and playing in a jazz band in Acapulco. After studying philosophy at Dartmouth College (where he had made friends with screenwriter Buck Henry), and graduating in 1954, Rafelson was drafted into the U.S. Army and stationed in Japan. In Japan he worked as a disk jockey, translated Japanese films and was an adviser to the Shochiku Film Company as to what films would be financially successful in the United States. In an interview with critic Peter Tonguette, Rafelson said he was fascinated by the films he saw in Japan, especially those of Yasujirō Ozu, whose original approach to editing captivated him as a young man: "I'd have to watch an Ozu movie over and over again—say, Tokyo Story—and I was hypnotized by the stillness of his frames, his sureness of composition," he said. "So, I suppose my own aesthetic evolved from looking at certain kinds of pictures—Bergman and Ozu and John Ford, if you will."

Rafelson began dating Toby Carr in high school and they later married in the mid-1950s. The couple had two children: Peter Rafelson, born in 1960, and Julie Rafelson, born in 1962. Toby Rafelson was a production designer on many films, including her husband's Five Easy Pieces, The King of Marvin Gardens, and Stay Hungry, as well as Martin Scorsese's Alice Doesn't Live Here Anymore and Jonathan Demme's Melvin and Howard.^{[better source needed]}

Rafelson's first professional job was as a story editor on the TV series Play of the Week for producer David Susskind in 1959. The series produced televised stage plays from contemporary and classical authors. Rafelson's job required him to read hundreds of plays, select which were to be produced, and write some additional dialogue uncredited. Rafelson's first writing credits were for an episode of the TV series The Witness in 1960 and an episode of the series The Greatest Show on Earth in 1963.

In June 1962, Rafelson and his family moved to Hollywood, where he began working as an associate producer on television shows and films at Universal Pictures, Revue Productions, Desilu Productions and Screen Gems. After an argument with Lew Wasserman over creative differences on the show Channing, culminating in Rafelson sweeping "awards, medallions, souvenir ashtrays, and other tchotchkes" from Wasserman's desk, he was fired.

In 1965, while working at Screen Gems, Rafelson met fellow producer Bert Schneider. They became fast friends and created the company Raybert Productions together that year. Raybert would later become BBS Productions and produce films as a subsidiary of Columbia Pictures. Rafelson and Schneider's first project was a television series about a rock 'n' roll group. Rafelson said that the idea for the show, which was inspired by his own misadventures while playing in a band in Mexico, predated A Hard Day's Night. Rafelson said, "I had conceived the show before The Beatles existed," and it was based on his time as an itinerant musician more "interested in having fun" than "in earning a living." Raybert Productions sold the idea to Screen Gems and, when they were unable to get either the Dave Clark Five or the Lovin' Spoonful for the show, ran ads in Daily Variety and The Hollywood Reporter for musicians. The band that they created was The Monkees and the series ran from 1966 until 1968.

The Monkees was immediately a success with audiences and, despite the band being a manufactured act, was particularly popular with the youth demographic at the time. Rafelson and Schneider won the Emmy Award for Outstanding Comedy Series as producers in 1967. Rafelson has said that "the whole show was created in effect in the editing room. The tempo was of paramount importance...I had to direct one or two of the shows for television to set the pattern of how these things should be made." Rafelson had said that "of the first 32 shows, 29 were directed by people who had never directed before, including me. So the idea of using new directors not perhaps too encumbered by traditional ways of thinking was initiated on that series and just continued on the movies we made later." He has cited the series' "radically different way of cutting and doing a half hour comedy because there were interviews that were interspersed [and] there was documentary footage."
