触摸板（TouchPad或TrackPad），是一种广泛应用于笔记本电脑上的输入设备。其利用感应用户手指的移动来控制指针的动作。

触摸板可以视作是一种鼠标的替代物。在其他一些便携式设备上，如个人数码助理与一些便携影音设备上也能找到触摸板。受到设计限制，触摸板通常不大于20平方厘米。这其中以苹果公司MacBook Pro配备的多点触控板最为出色。它利用了苹果的multi-touch技术。这项技术最早由FingerWorks（旧金山的一家小公司，后被苹果收购）研发并申请专利，后来首先被应用在iPhone上。

A touchpad is a pointing device featuring a tactile sensor a specialized surface that can translate the motion and position of a user's fingers to a relative position on the operating system that is outputted to the screen. Touchpads are a common feature of laptop computers, and are also used as a substitute for a mouse where desk space is scarce. Because they vary in size, they can also be found on personal digital assistants (PDAs) and some portable media players. Wireless touchpads are also available as detached accessories.
