Kłodzko Land (Czech: Kladsko; German: Glatzer Land; Polish: ziemia kłodzka) is a historical region (ziemia) in southwestern Poland. Geographically speaking Kłodzko Land consists of the Kłodzko Valley and the surrounding Sudetes mountains. It is named after its capital city, Kłodzko.
Historically, the area may have been part of Great Moravia under King Svatopluk I by the late 9th century, though the extent of his realm is disputed. According to the 1191 Chronica Boëmorum by Cosmas of Prague, the castle of Kłodzko on the road from Prague to Wrocław in 981 was a possession of the Bohemian nobleman Slavník.
During the rivalry between the Přemyslid dukes Boleslaus III and Jaromir in 1003, the Polish king Bolesław I Chrobry invaded Bohemia, but had to pull back the next year, facing the forces of King Henry II of Germany. In turn the Bohemian duke Bretislaus I campaigned the adjacent northern territory of Silesia after Bolesław's death in 1025. An armistice mediated by Henry II, Holy Roman Emperor since 1014, demarcated the spheres of influence, leaving Kłodzko with Bohemia.
