Lost artworks are original pieces of art that credible sources or material evidence indicate once existed but that cannot be accounted for in museums or private collections, as well as works known to have been destroyed deliberately or accidentally or neglected through ignorance and lack of connoisseurship.

Research and recovery efforts

The Art Loss Register is a commercial computerized international database which captures information about lost and stolen art, antiques and collectables. It is operated by a commercial company based in London.

In the U.S., the FBI maintains the National Stolen Art File, "a database of stolen art and cultural property. Stolen objects are submitted for entry to the NSAF by law enforcement agencies in the U.S. and abroad."

A number of search and recovery efforts were created in response to major loss events, notably: Monuments, Fine Arts, and Archives program ("Monuments Men"), 1943–1946 Bureau of Revindication and Damages (Poland), operated from 1945 to 1951 Bureau of the Government Representative for Polish Cultural Heritage Abroad, 1991-
