A group of rides and other entertainment attractions assembled for the purpose of entertaining large numbers of people. An amusement park is more elaborate than a simple city park or playground, usually providing attractions meant to cater to children, teenagers, and adults.

Amusement parks evolved in Europe from fairs and pleasure gardens which were created for people’s recreation. The oldest amusement park in the world (opened 1583) is Bakken, at Klampenborg, north of Copenhagen, Denmark. In the United States, world's fairs and expositions were another influence on development of the amusement park industry.

Most amusement parks have a fixed location, as compared to traveling funfairs and carnivals. These temporary types of amusement parks are usually present for a few days or weeks per year, such as funfairs in the United Kingdom, and carnivals (temporarily set up in a vacant lot or parking lots) and fairs (temporarily operated in a fair ground) in the United States. The temporary nature of these fairs helps to convey the feeling that people are in a different place or time.
