Dujardin said of his character: "If George Valentin could speak, he would say 'Wow! Victorie! Genial! Merci!'"
The film also won the Oscars for best original score and best costumes.
Martin Scorsese's Hugo also won five Oscars, mainly in technical categories.
Meryl Streep won best actress for her portrayal of former British Prime Minister Margaret Thatcher in The Iron Lady - her 17th Oscar nomination and third Oscar win.
Streep won a third Oscar, having been nominated 17 times
She thanked the Academy "for this inexplicably wonderful career".
"When they called my name I had this feeling I could hear half of America going: 'Aww no. Not her again'. But, you know, whatever.
"I look out here and I see my life before my eyes. My old friends, my new friends. This is such a great honour but the thing that counts the most for me is the friendships... Thank you. All of you, departed and here," she added.
Dujardin broke into his native French language in celebration shouting: "Wow, victory!"

1929 was the last year that a silent movie won an Oscar.
Canadian actor Christopher Plummer became the oldest Oscar winner at 82 by taking the best supporting actor prize.
