Den nya nordiska floran ("The new Nordic flora") is a book of Swedish flora from 2003 by Bo Mossberg and Lennart Stenberg, with illustrations by Bo Mossberg. It contains descriptions, illustrations and distribution maps of all plants in Sweden, Denmark, Norway (including Svalbard), Finland, Faroe Islands and Iceland, a total of more than 3,250 species. It is a sequel to the earlier book Den nordiska floran. It has been called indispensable as a reference book, but criticized for being too heavy to be a field flora.
