A casino (also known as a gambling house, and in some jurisdictions as a gaming establishment) is an institution where people can play various games of chance for cash or other prizes. These games are usually combined with entertainment and dining options. In addition to casino games, some casinos host live entertainment such as stand-up comedy, concerts, and sports. Some casinos also serve alcohol.

The precise origin of gambling is unknown, but it has been a popular activity throughout history in every culture. The modern casino industry is estimated to be worth $231 billion, and the largest casinos have become opulent entertainment complexes offering five-star hotel rooms, Michelin-starred restaurants, designer shops, and top-billed entertainers.

These giant casinos often feature a dazzling array of slot machines and table games. They have massive indoor spaces and sprawling acreage, and they are designed to appeal to the highest-income tourists. They are often adorned with expensive artwork, opulent decorations, and state-of-the-art technology.

A casino can be found in many places around the world, but it is most famous for its gambling facilities in Las Vegas and Macau. In recent years, some casinos have expanded into resorts and have begun to compete with theme parks and other destinations for tourist dollars. This competition has caused some traditional casinos to close, but newer ones are being built in areas with a growing interest in gambling. Some of the most famous casinos have appeared in movies and television, including the Monte Carlo Casino in Monaco, which has been depicted in multiple James Bond films, and the Casino de Paris in France.
