Nové Zámky ( pronunciation ; Hungarian: Érsekújvár, German: Neuhäus[e]l, Turkish: Uyvar, Latin: Novum Castrum) is a town in southwestern Slovakia.

The town is located on the Danubian Lowland, on the Nitra River, at an altitude of 119 metres. It is located around 100 km from Bratislava and around 25 km from the Hungarian border. It is a road and railway hub of southern Slovakia.

The town lies in the temperate zone and has a continental climate. Annual average temperature reaches around 10 °C (50.0 °F), with the warmest month being July with an average of 20 °C (68 °F) and the coldest January with −2 °C (28 °F). Average annual precipitation is 556 mm.

The town has a distinguished history. From the second half of the 10th century until 1918, it was part of the Kingdom of Hungary. A fortress was built, against the Ottoman Turks, on the site of an older settlement in the years 1573–81. Between 1589 and 1663, the settlement was the seat of the Captaincy of Lower Hungary. The town developed around the fortress. The huge new fortress was one of the most modern fortresses in Europe when it was built, a prime example of the star fortress which was considered to be adapted to the advance in artillery in the preceding centuries. (In fact, the Hungarian name means "the archbishop's new castle".)
