Graphing Calculator may refer to:

• Graphing calculators, calculators that are able to display and/or analyze mathematical function graphs
• NuCalc, a computer software program able to perform many graphing calculator functions
• Grapher, the Mac OS X successor to NuCalc

A graphing calculator (also graphics / graphic calculator) is a handheld calculator that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are also programmable, allowing the user to create customized programs, typically for scientific/engineering and education applications. Because they have large displays, graphing calculators also typically display several lines of text and calculations at the same time.
