[[File:Option-buttons2.gif|thumb|Four options on a radio button. When a new option is chosen, the previously chosen option is unselected.]]
A '''radio button''' or '''option button'''<ref>{{Cite web |title=About Option Buttons |url=https://docs.oracle.com/cd/E14004_01/books/Fundamentals/fund_aboutrecordsfields006.htm |access-date=2025-02-02 |website=docs.oracle.com}}</ref> is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options.<ref name="micro"/> The singular property of a radio button makes it distinct from [[checkbox]]es, where the user can select and unselect any number of items.

Radio buttons are arranged in groups of two or more and displayed on screen as, for example, a list of circular holes that can contain white space (for unselected) or a dot (for selected). Each radio button is normally accompanied by a label describing the choice that the radio button represents. The choices are mutually exclusive; when the user selects a radio button, any previously selected radio button in the same group becomes deselected (making it so only one can be selected). Selecting a radio button is done by clicking the mouse on (or touching the screen over) the button, or the caption, or by using a keyboard shortcut.
