A slider or track bar is a graphical control element with which a user may set a value by moving an indicator.{{Cite book |last=Eick |first=Stephen G. |chapter=Data visualization sliders |date=1994-11-02 |title=Proceedings of the 7th annual ACM symposium on User interface software and technology - UIST '94 |chapter-url=https://dl.acm.org/doi/abs/10.1145/192426.192472 |location=New York, NY, USA |publisher=Association for Computing Machinery |pages=119–120 |doi=10.1145/192426.192472 |isbn=978-0-89791-657-8 |quote=Sliders are a general-purpose user input mechanism enabling users to specify a single input value from a well-defined range. They are widely used in all graphical user-interface systems.... Sliders are easy to use, intuitive, and provide a sensitive mechanism for specifying values. Sliders have a threshold bar positioned within a scale that the user manipulates with a mouse to select a value. Graphical input tools with similar function include dials, bars, pointers, gauges, and potentiometers.}} In some cases the user may also click on a point on the slider to change the setting. It is different from a scrollbar in that it is not continuous but used to adjust a value without changing the format of the display or the other information on the screen.

Its most popular use is for viewing and jumping to a playback position in media player software.{{citation needed|date=May 2025}}
