In February 1986, Raymond and his brother Jacques joined the World Wrestling Federation, debuting during a tour of Australia. During their first year with the company, they faced and defeated such duos as The Hart Foundation (Bret Hart and Jim Neidhart), The Moondogs, Jimmy Jack and Dory Funk, Jr., and The Dream Team (Greg Valentine and Brutus Beefcake).
Although they lost their match at WrestleMania III in 1987 to Valentine and Beefcake, they briefly upset The Hart Foundation for the WWF Tag Team Championship on August 10 of that year. The decision was reversed to a disqualification and the championship returned, since the challengers initially won after using Jimmy Hart's megaphone as a weapon.
After two years in the Federation, The Fabulous Rougeaus (Jacques and Raymond) turned heel when they participated in an angle in which the Canadian brothers were announced as "From Canada, but soon to relocate to the United States", and had an intentionally annoying entrance theme in which they sang (partly in French) about being "All-American Boys" as well as now having Jimmy Hart as their manager (The Rougeaus were also briefly billed as being from Memphis, Jimmy Hart's home city). They also waved tiny American flags, infuriating fans, who questioned their sincerity, and humorously attempted to start "USA!" chants, which led to further negative fan "heat". They feuded with The Killer Bees, The Hart Foundation (who had turned face in between), The Bushwhackers and The Rockers during their heel run.
Raymond went into semi-retirement three months after SummerSlam in 1989. His last match in the WWF was at the Royal Rumble in 1990, which the Rougeau Brothers lost to The Bushwhackers.
In late 1992, Rougeau replaced Edouard Carpentier as the play-by-play commentator for the French syndicated WWF programming. He commentated alongside Jean Brassard from 1994-1999, then for a short period with Philippe Hartman from 2000-2002.
As his brother was still an active competitor as one half of The Quebecers alongside Pierre, Pierre turned and started attacking Jacques. Raymond left the commentary table and ran to the ring to save his brother. Rougeau later accompanied Jacques in his first retirement match in the WWF, held in Montreal.
Rougeau came out of retirement in August 8, 1996 to face Owen Hart in a boxing match at during a WWF house show, despite not being active as a competitor for years.
Rougeau came out of retirement again in March 1998, when he teamed with Jacques and Carl Ouellet to defeat Adam Copeland, Shawn Stasiak and Tom Brandi in a dark match for WWF Shotgun Saturday Night.
Rougeau left the WWF in early 2002 when it stopped producing French editions of its programming.
In May 2017, it was announced that Rougeau would return to WWE as a French language commentator.
