Hosena (Sorbian: Hóznja) is a borough (Ortsteil) of the town of Senftenberg in Brandenburg, Germany.

In the early historical period, Hosena was part of the Sorbian district of Milska and a Folwark to the domain of Hoyerswerda, with a herd of sheep and three leasehold mills.

Since the end of the 19th century, Hosena has become famous for industrial processing of crystalline quartz sand and for glass making.

Prior to that, the settlement had been among the poorest heathland villages, since the barren, largely infertile sandy soil yielded only meager harvests.

It had been founded as a result of industrialization; railroad workers and employees of the nearby glass works and sand quarries lived there.

A 2.6 m tall marker column was erected there in July 2009[2] Today a tilted observation tower stands at the boundary of Hosena on the shore of the Senftenberger See.

Joachim Sauer, professor of Physical and Theoretical Chemistry at Humboldt University of Berlin and husband of German Chancellor Angela Merkel, was born in Hosena.
