Uelzen (German pronunciation:[ˈʔʏltsən], Low German Ülz’n) is a town in northeast Lower Saxony, Germany, and capital of the county of Uelzen. It is part of the Hamburg Metropolitan Region, a Hanseatic town and an independent municipality.

Uelzen is characterised by timber-framed architecture and also has some striking examples of North German brick Gothic. But the county town earned pan-regional fame when Friedensreich Hundertwasser was selected to redesign the station. The final work of the celebrated Viennese artist and architect was ceremonially opened in 2000 as the Hundertwasser Station, Uelzen and has since been a popular tourist magnet.
