A UI element consisting of a box or strip of icons (or menu items) corresponding to actions which can be performed.

Games on personal computers, designed to be used with a one or two-button mouse, use these to allow the player to select which action he wants to perform. Console games generally assign different controller buttons to these functions, but, particularly when the buttons are assignable, may keep an ActionBar on screen as a visual reference as to which options are currently equipped. The ActionBar can also represent the player's inventory of usable items.

A variation seen in later games was to replace the ActionBar with a pop-up display of actions which appear radially around the character sprite. Such a usage is commonly called a "RingMenu".

!!Examples:

* One of the three main styles of interface for [[AdventureGame adventure games]], particularly early {{Sierra}} and LucasArts games.
* ''The Legend of Zelda'' games, from their earliest incarnation, kept an action bar on-screen to show which items Link has equipped.
* ''VideoGame/MetroidPrime'' and its sequels have visual indicators at the bottom of the screen to show which weapon and display Samus has armed.
* The RingMenu-style ActionBar was common in late Lucas Arts adventure games, and is currently best known from its use in ''The Sims''.
* ''Natural Selection'', a multiplayer mod for ''VideoGame/{{Half-Life}}'', ups the ante with a full-featured Action Menu that can be quickly called and navigated with a middle click.
* ''RatchetAndClank'' uses a RingMenu as a weapon select.
** ''VideoGame/SaintsRow1'' and its sequel do this as well.
* Due to their huge assortment of building tools, most building simulation games such as the ''VideoGame/SimCity'' series have an Action Bar somewhere in the screen.
* The RingMenu makes an appearance in ''SecondLife''
* Common in many [=MMOs=] such as ''WorldOfWarcraft'' and ''CityOfHeroes''. It's not uncommon for higher-level characters to have many action bars, with those who have maxed-out their capabilities viewing the game through a kind of narrow window in between their action buttons.
