Toy guns are toys which imitate real guns, but are designed for recreational sport or casual play by children. From hand-carved wooden replicas to factory-produced pop guns and cap guns, toy guns come in all sizes, prices and materials such as wood, metal, plastic or any combination thereof. Many newer toy guns are brightly colored and oddly shaped to prevent them from being mistaken for real firearms.

Nerf is a toy brand formed by Parker Brothers and currently owned by Hasbro. Most of the toys are a variety of foam-based weaponry, with other Nerf products including balls for sports such as American football, basketball, and baseball. Their best known toys are their dart guns that shoot ammunition made from "Nerf foam". Their primary slogan, introduced in the 1990s, is "It's Nerf or Nothin'!". Annual revenues under the Nerf brand are approximately US$400 million.
