Borovno () is a municipality and village in Plzeà Â-South District in the Plzeà  Region of the Czech Republic. It has about 100 inhabitants.
The name was derived from the Czech word borovice, borový les ("pine, pine forest"), which refers to the composition of the local forest at the time of the settlement of the area.
Borovno is located about southeast of Plzeà Â. The western part of the municipal territory with the village lies in the à  vihov Highlands, but most of the territory lies in the forested landscape of the Brdy Highlands. The highest point is at above sea level. The Bradava Stream flows along the southern municipal border and supplies three small fishponds.
Borovno was founded in the 14th century at the latest, during the settlement of the area by the lords of Roà ¾mitál. Later it was merged with the Miroà ¡ov estate and from 1616, it was part of the Spálené Poà ÂÃÂÃÂàestate. The greatest development of Borovno occurred at the end of the 18th century, when smelters were established in the vicinity of the village. In the early 19th century, the development ended.
In 1945, at the end of World War II, Borovno was liberated by American troops who stopped their advance here. From 1968 to 1990, a military base of the Warsaw Pact armies was located in the territory of Borovno.
From 1980 to 1990, Borovno was merged with the town of Spálené Poà ÂÃÂÃÂÃÂ. Since 1 September 1990, the municipality has been separate again.
The I/19 road (the section connecting Plzeà  with Tábor) runs through the municipality.
A remnant of the military base is Javor 51, a unique concrete warehouse that was used to store nuclear munitions. Today it is open to the public as the Atom Museum.
