The 1962 European Judo Championships were the 11th edition of the European Judo Championships, and were held in Essen, West Germany on 12 and 13 May 1962. The Championships were held in two separate categories: amateur and professional. The amateur contests were subdivided into weight classes, experience classes, and a separate team competition. The professional contests were subdivided only into weight classes. It was the first edition of the European Judo Championships to host judokas from the Socialist countries, though they did not participate in the professional contests as professional sports were banned in those countries. Contrary to the modern Olympic-based practice of entering one athlete per weight class, more than one representative of a single national team was allowed to qualify for participation in each event. The professional category was established for those teaching judo, and hence not considered amateurs in the Olympics' category. This later precluded Anton Geesink from participating in the amateur weight classes at the judo event of the 1964 Olympics.
