A home video game console is a video game console that is designed to be connected to a display device, such as a television, and an external power source as to play video games. While initial consoles were dedicated units with only a few games fixed into the electronic circuits of the system, most consoles since support the use of swappable game media, either through game cartridges, optical discs, or through digital distribution to internal storage.

There have been numerous home video game consoles since the first commercial unit, the Magnavox Odyssey in 1972. Historically these consoles have been grouped into generations lasting each about six years based on common technical specifications. As of 2025^[update], there have been nine console generations, with the current leading manufacturers being Sony, Microsoft, and Nintendo, colloquially known as the "Big 3".

A home video game console is a pre- designed piece of electronic hardware that is meant to be placed at a fixed location at one's home, connected to a display like a television screen or computer monitor, and to an external power source, to play video games on using one or more video game controllers. This differs from a handheld game console which will have a built-in screen, controller buttons/features, and a power supply like a battery or battery pack.

Earlier home consoles were typically built from a selection of standard and highly customized integrated computer chips, packaged onto circuit boards and cases. Over time, home console design has converged to a degree with personal computers, using similar component and system design, including standardization with main computer chip architecture. Consoles remain as fixed systems, lacking the customization options that personal computer components have, and most consoles include customized components to maximize space and reduce power consumption to provide the best performance for game playing, while lowering costs with reduced storage and memory configurations.

Home video game consoles typically can play a multitude of games, offered either as game cartridges (or ROM cartridges), on optical media like CD-ROM or DVD, or obtained by digital distribution. Early consoles, also considered dedicated consoles, had games that were fixed in the electronic circuitry of the hardware. Some facets may be controlled by switching external controls on the console but the games could not be changed themselves.

Most home consoles require a separate game controller, and may support multiple controllers for multiplayer games. Some console games can only be played with special, unconventional game controllers, such as light guns for rail shooters and guitar controllers for music games. Some consoles also possess the ability to connect and interface with a particular handheld game system, which certain games can leverage to provide alternate control schemes, second screen gameplay elements, exclusive unlockable content or the ability to transfer certain game data.

The first commercial video game console was the Magnavox Odyssey, developed by a team led by Ralph H. Baer and released commercially in 1972. It was shortly followed by the release of the home version of Pong by Atari Inc. in 1975 based on the arcade game. A number of clones of both systems rushed to fill the nascent home console market and the video game industry suffered a small recession in 1977 due to this.

The Fairchild Channel F, released in 1976, was the first console to use game cartridges, which was then used by the Atari VCS and several other consoles of the second generation and led to a second boom in the video game industry in the United States and around the globe. During this time, Atari Inc. had been sold to Warner Communications, and several programmers left the company and founded Activision, becoming the first third-party developer. Activision's success led to a rush of new developers creating games without any publishing controls for these systems. The market became flooded with games, and combined with the rising popularity of the personal computer and the economic recession of the early 1980s, led to the video game crash of 1983 in the U.S. market. Nintendo, which had released its Family Computer console in Japan that year, took several cautionary steps to limit game production to only licensed games, and was able to introduce it, rebranded as the Nintendo Entertainment System (NES) in 1985 into the U.S. market. The NES helped to revive the console market and gave Nintendo dominance during the late 1980s.
