The Marvel movie, the second biggest box office hit of all time, took wins for best movie, villain (Josh Brolin's Thanos) and hero (Robert Downey Jr's Iron Man.)
But US Supreme Court Justice Ruth Bader Ginsburg, the diminutive, 86-year-old liberal judge, was voted best real-life hero, cementing her status as an unexpected pop culture icon, especially among women. She did not attend the MTV ceremony in the California beach city of Santa Monica.
The MTV Movie and TV awards usually focus on crowd-pleasers and are an irreverent antidote to the more serious winter Hollywood awards season. Winners get popcorn shaped trophies and are chosen by fans voting online.
But while medieval fantasy "Game of Thrones" was named best TV show on Monday, other awards went to darker fare.
"Surviving R. Kelly," in which seven women spoke on camera about what they said was years of sexual and emotional abuse by the "I Believe I Can Fly" singer, won best documentary.
The Lifetime network documentary led to Kelly being dropped by his record company and to criminal charges in Chicago of aggravated sexual assault involving four women, three of them minors. Kelly has pleaded not guilty and is awaiting trial.
"Survivors walked through the fire and then stood again to tell this story," Brie Miranda Bryant, an executive with Lifetime, said in an acceptance speech.
Elisabeth Moss, star of "The Handmaid's Tale," took the award for best performance in a TV show, a category that was entirely made up of women. The bleak drama series portrays a near future in which women are stripped of all their rights, including working and reading.
Brie Larson's "Captain Marvel" triumphed in the best fight category, while MTV's popular best kiss award went to newcomers Noah Centineo and Lana Condor from the Asian-led teen movie "To All the Boys I've Loved Before."
"Love who you want to love, and don't let anyone tell you otherwise," Condor, 22, told the audience.
Actor, producer and wrestler Dwayne "The Rock" Johnson was given the Generation award for a career that encompasses more than 30 film and TV shows, including the "Fast and Furious" movie franchise.
Johnson told the audience that when he first came to Hollywood some 15 years ago, the entertainment industry didn't know how to handle a 6-foot-4-inch, muscled, half black, half Samoan man, "so I decided I wasn't going to conform to Hollywood, Hollywood was going to conform to me".
Breakout singer Lizzo gave her first awards show performance with her hit single "Juice," an anthem to self-esteem.
"Girls Trip" actress Jada Pinkett-Smith was given the annual Trailblazer award for a career that includes author, fashion designer, women's rights activist and funder of youth programmes.
