Kopidlno is a town in Jičín District in the Hradec Králové Region of the Czech Republic.

Kopidlno consists of five municipal parts (in brackets population according to the 2021 census):[2] The name Kopidlno is probably derived from the name of medicinal plants found in the surrounding forests (Asarum europaeum, colloquially known in Czech as kopidlen).

According to other theories, it might be derived from the Old Czech kopjo dlinno (i.e. 'long spear') or from kopidlo ('hay stake').

It lies mostly in the Central Elbe Table, but the municipal territory also extends to the Jičín Uplands in the north and east.

Among the next owners were many notable noble families, including Haugwitz, Trčka of Lípa, Thurn und Taxis and Schlick, and individuals Albrecht von Wallenstein and Ludwig of Dietrichstein.
