网页快捷键，或称为Access Key或accesskey，是指在网页浏览器中输入特定之电脑键盘按键，以快速地在网页中不同区域切换。这项概念在公元1999年被提出且立刻得到各家浏览器的支持。网页快捷键最受到注目的是它提供某些身心障碍人士能更加方便且有效率地浏览网页。

网页快捷键并非一般电脑软件的快捷键（如Ctrl + s可以保存文件之类的组合按键），而是由网页设计师直接在HTML语言中指定。HTML语言中针对网页快捷键的语法为accesskey="h"，其中h即为被指定之网页快捷键。网页快捷键在HTML中仅需指定为单一字符，但不同浏览器有不同启动网页快捷键之组合键，因此大多需要同时接下数个按键才能完整地使用网页快捷键。

In a web browser, an access key or accesskey allows a computer user to immediately jump to a specific part of a web page via the keyboard. They were introduced in 1999 and quickly achieved near-universal browser support.

In the summer of 2002, a Canadian Web Accessibility consultancy did an informal survey to see if implementing accesskeys caused issues for users of adaptive technology, especially screen reading technology used by blind and low vision users. These users require numerous keyboard shortcuts to access web pages, as “pointing and clicking” a mouse is not an option for them. Their research showed that most key stroke combinations did in fact present a conflict for one or more of these technologies, and their final recommendation was to avoid using accesskeys altogether.
