网域名称转址（英语：URL redirection，或称网址重定向或网域名称转址），是指当用户浏览某个网址时，将他导向到另一个网址的技术。常用在把一串很长的网站网址，转成较短的网址。因为当要传播某网站的网址时，常常因为网址太长，不好记忆；又有可能因为换了网络的免费网页空间，网址又必须要变更，不知情的用户可能会认为网站关闭了。这时就可以用网络上的转址服务了。这个技术使一个网页是可借由不同的统一资源定位符（URL）链接。

URL redirection, also called URL forwarding, is a World Wide Web technique for making a web page available under more than one URL address. When a web browser attempts to open a URL that has been redirected, a page with a different URL is opened.

Similarly, domain redirection or domain forwarding is when all pages in a URL domain are redirected to a different domain, as when wikipedia.com and wikipedia.net are automatically redirected to wikipedia.org.
