This is a map of the known world from George R. R. Martin’s A Song of Ice and Fire saga. This map was included as a poster in a collection of twelve map posters sold as The Lands of Ice and Fire. This is, for now, considered the definitive world map of the Song of Ice and Fire world. Several similar fan maps included on this site have been rendered obsolete  and inaccurate by this map’s publication. The map and the novels have clearly indicated that there are lands in this world not detailed here and therefore it is possible a more complete map will be published in the future.
