Nagybörzsöny (German: Deutschpilsen or Deutsch Pilsen) is a village in Pest County, Hungary.

The earlier name of this village was Börzsöny and it was, in all probability, founded in the 12th century by King Géza II of Hungary.

In medieval times, it was able to grow into a full-fledged mining town due to its proximity to various ores, including gold.

In 1789, Pál Kitaibel officially discovered the element Tellurium in the Nagybörzsöny ores.

The element eventually played an important role in the making of the outer shell of the first atom bomb.
