XBEL, or the XML Bookmark Exchange Language, is an open XML standard for sharing Internet URIs, also known as bookmarks (or favorites in Internet Explorer).

An example of XBEL use is the XBELicious application, which stores Del.icio.us bookmarks in XBEL format. The Galeon and Konqueror web browsers use XBEL as the format for storing user bookmarks.

XBEL was created by the Python XML Special Interest Group "to create an interesting, fun project which was both useful and would demonstrate the Python XML processing software which was being developed at the time," .
