IntelliMouse is a brand of computer mice from Microsoft. The IntelliMouse series is credited with a number of innovations. For example, Microsoft was among the first mouse vendors to introduce a scroll wheel,^[1] an optical mouse, and dedicated forward- and back-buttons on the side of the mouse for easier web-browsing.

Microsoft also introduced one of the first mainstream ergonomic mice, the Microsoft Natural Wireless Laser Mouse 6000. This mouse features an unusual design, tilting the user's hand at an angle to reduce compression of the nerves in the wrist (unlike conventional mice, which have the user's palm facing down).

As of 2013 the IntelliMouse lineup includes a number of models, both wired and wireless, and including the IntelliMouse Explorer 3.0. They use IntelliPoint drivers. The main competitor is Logitech.

The IntelliMouse was introduced in 1996,^[2] and the IntelliMouse Explorer in 1999.^[3]

All older Intellimice share their design with the older Microsoft Mouse.
