Fandor was a German toy company that specialized in toy trains, particularly toys styled after American trains. It was founded by Joseph Kraus and his cousins, Milton and Julius Forcheimer, all from Nuremberg, Germany. The name was derived from the names of the founders' mothers, Dora and Fanny.

Protective tariffs following World War I made it difficult for German firms to compete with American toy companies, so the Forcheimer brothers immigrated to the United States, taking one of Fandor's engineers, John C. Koerber, with them, where they founded the U.S. company Dorfan.
