Roznov is a town located in Neamț County, Western Moldavia, Romania.

The town was first mentioned in 15th century documents, and was probably founded by German settlers, along with Târgu Neamț: historians speculate that the original name was Rosenhoff.

Built between 1884 and 1892 in a Russian style unique to the region, it was founded by the boyar Gheorghe Ruset Roznovanu, whose family had an estate at Roznov for many years.

The interior frescoes were completed in 1915 by the artist Costin Petrescu, under the aegis of banker, oil magnate, vineyard owner, and art collector Hector Economos, who bought the Roznov estate after the Ruset Roznovanu family died out.

The main economy of Roznov consists of the production of adhesives, chemicals used on agriculture, and sulphuric acid.
