The Conference of European National Librarians (CENL) is a foundation under Dutch law with the aim of increasing and reinforcing the role of national libraries in Europe, in particular in respect of their responsibilities for maintaining the national cultural heritage and ensuring the accessibility of knowledge in that field. Members of CENL are the national librarians of all Member States of the Council of Europe.

The conference currently consists of 49 members from 46 European countries. The European Commission has subsidised various CENL projects.
