Hammer Bro., also known as Hammer Brothers or Hammer Bros. (Japanese: ハンマーブロス^?, Hepburn: Hanmā Burosu) is a recurring enemy in the Mario series of video games. Created by Japanese video game designer Shigeru Miyamoto, it is a subspecies of Koopa Troopa that walks upright and attacks by throwing hammer projectiles at the player character. Different variations of the Hammer Bro., named after the type of projectile they throw, include Boomerang Bro., Fire Bro., Sledge Bro., Sumo Bro, and Ice Bro. The Hammer Bro. has appeared in nearly every Super Mario game since its first appearance in Super Mario Bros., also appearing in various animated and printed adaptations of the franchise.

Hammer Bro. first appeared in Super Mario Bros., where they would jump from platforms and throw hammers at Mario. In the game, they were usually found in pairs. They later appeared in its sequel, Super Mario Bros.: The Lost Levels, where they were found more commonly. Although they were absent in Super Mario Bros. 2, they did appear in Super Mario Bros. 3, in which they behaved in the same way as they did in the original game. Also, more varieties of Hammer Bro. were added, including the Boomerang Bro., whose boomerangs returned to them, the Fire Bro., who spat fireballs, and the Sledge Bro., who was considerably larger and could cause an earthquake when he landed from a jump. Super Mario Bros. 3 also featured the Hammer Bros. Suit, which granted Mario and Luigi the ability to throw hammers of their own and also conferred immunity against fire attacks while ducking.
