XHTML MP（XHTML Mobile Profile），它是定义在WAP 2.0上面的标记语言（markup language）。XHTML MP是XHTML的子集，在XHTML MP出现之前，WAP网站的开发者们只能用WML和WML script来创建WAP的网站。而与此同时，web的开发者们却在用强大得多的HTML、CSS、XHTML等来进行传统网站的开发。所以XHTML MP的目标就是浏览者在WAP和web上获得尽可能相似的浏览体验。

XHTML Mobile Profile (XHTML MP) is a hypertextual computer language standard designed specifically for mobile phones and other resource-constrained devices.

It is an XHTML document type defined by the Open Mobile Alliance. XHTML-MP is derived from XHTML Basic 1.0 by adding XHTML Modules, with later versions of the standard adding more modules. However, for certain modules, XHTML-MP does not mandate a complete implementation so an XHTML-MP browser may not be fully conforming on all modules.
The XHTML MP 1.2 DTD is the current recommendation, finalized in March 2008.
