Quilt is a proposed XML Query Language. Its name suggests both the way in which concepts from several languages were pulled together to make a new query language, and the way in which Quilt queries can combine information from diverse data sources into a query result with a new structure of its own.

Quilt has been presented as a proposal to the W3C XML Query Working Group, and that group has adopted Quilt as the basis for development of a new language called XQuery . Development work is now focused on XQuery rather than on the Quilt proposal.
