Internet Explorer Mobile或IE Mobile是一款由微软公司开发的网页浏览器，它装载于为手持式个人计算机开发的Windows Mobile和Windows Phone中，与微软的Internet Explorer有很多相似之处；然而，它与Internet Explorer并不是基于同样的排版引擎。IE Mobile在Windows Phone上的版本比Windows Mobile平台上的更多功能。

Internet Explorer Mobile (formerly named Pocket Internet Explorer; commonly abbreviated to IE Mobile) is a mobile browser developed by Microsoft, based on versions of the Trident layout engine. IE Mobile comes loaded by default with Windows Phone and Windows CE. Current versions of Internet Explorer Mobile (since Windows Phone 8) are based on the desktop version of Internet Explorer. Older versions however, called Pocket Internet Explorer (found on Windows Phone 7 and Windows Mobile), are not based on the same layout engine.
