Koblenz (also Coblenz in English and pre-1926 German spellings; also Coblence in English and French) is a German city situated on both banks of the Rhine at its confluence with the Moselle, where the Deutsches Eck (German Corner) and its monument (Emperor William I on horseback) are situated.

As Koblenz was one of the military posts established by Drusus about 8 BC, the town celebrated its 2000th anniversary in 1992.

The name Koblenz originates from Latin (ad) confluentes, confluence or "(at the) merging of rivers". Subsequently it was Covelenz and Cobelenz. In the local dialect the name is Kowelenz.

After Mainz and Ludwigshafen am Rhein, it is the third largest city in Rhineland-Palatinate, with a population of c. 106,000 (2006). Koblenz lies in the Rhineland, 92 kilometers (57 mi) southeast of Cologne by rail.
