Râșnov Fortress (Romanian: Cetatea Râșnov, German: Rosenauer Burg, Hungarian: Barcarozsnyó vára) is a historic monument and landmark in Romania. It is situated in Râşnov, Brașov County, in the immediate vicinity of Brașov.

The fortress was built as part of a defence system for the Transylvanian villages exposed to outside invasions. A decisive aspect for building the fortress at its location was the route of the invading armies which were coming from the Bran pass and were passing through Râșnov, on their way to Braşov and other parts of the Burzenland region. The only chance of survival for the inhabitants of the area, including from Cristian and Ghimbav, was the refuge inside the refuge castle at Râşnov. Compelled to stay there for decades, the people of Râșnov and the nearby villages turned the fortification into their long-term place of residence.
