From what I have been taught (and what you find in most encyclopaedias, at least in the languages I know), Scandinavia is Denmark, Norway and Sweden. Some add Iceland and the Faroe Islands, because they speak related North Germanic languages which all descend from Old Norse. Finland has a completely different language, so is normally not included. The term which encompasses Scandinavia + Finland + Greenland is Nordic Countries (hence the Nordic, rather than Scandinavian, Council).Including Finland within Scandinavia is here regarded as one of the most common basic mistakes, the one in which the Geography teacher will usually test you. I have met many people from the Scandinavian kingdoms and all seemed to agree on this definition.
