Blešno is a municipality and village in Hradec Králové District in the Hradec Králové Region of the Czech Republic. It has about 400 inhabitants.

The name was probably derived from the false fleabane plant, called blešník in Czech. According to some sources, the name is derived from blecha (i.e. 'flea') and derisively meant "full of fleas".

Blešno is located about 5 kilometres (3 mi) east of Hradec Králové. It lies in a flat landscape in the Orlice Table. The Orlice River flows along the southern municipal border.

The first written mention of Blešno is from 1496, when it was bought by Mikuláš Trčka of Lípa and became part of the Opočno estate. After the estate was confiscated in 1636, Emperor Ferdinand II donated the estate to the Colloredo family. The Colloredo family, from 1789 known as the Colloredo-Mansfeld family, owned Blešno until the establishment of a sovereign municipality in 1849.
