Monopoly is the best-selling commercial board game in the world. Players compete to acquire wealth through stylized economic activity involving the buying, rental and trading of properties using play money, as players take turns moving around the board according to the roll of the dice. The game is named after the economic concept of monopoly, the domination of a market by a single provider.

It is published by Parker Brothers, an imprint of Hasbro. According to Hasbro, since Charles Darrow patented the game in 1935, approximately 750 million people have played the game, making it "the most played [commercial] board game in the world." The 1999 Guinness Book of Records cited Hasbro's previous statistic of 500 million people having played Monopoly. Games Magazine has inducted Monopoly into its Hall of Fame.
