Mr. Universe is a yearly contest in men's bodybuilding; competitors are welcome from around the world.

Mr. Universe is a kind of beauty contest, but much less publicized than its sister contest, Miss Universe. The rules are similar and the process similar to that of Miss Universe, but at Mr. Universe, there is less emphasis on beauty and facial attractiveness and instead the judging is based on the sheer muscularity of the contestants.

Among those who have held the title of Mr. Universe are:

• Yiye Avila (evangelist)
• Chris Dickerson
• Lou Ferrigno
• Mickey Hargitay (1955)
• Steve Reeves
• Arnold Schwarzenegger
