{{wide image|General view over bonn.jpg|900px|View over central Bonn as seen from the Stadthaus, including the [[Siebengebirge]], a hill range on the east bank of the [[Middle Rhine]]|5=center}}
===Topography===
Situated in the southernmost part of the [[Rhine-Ruhr]] region, Germany's largest metropolitan area with over 11 million inhabitants, Bonn lies within the [[States of Germany|German state]] of [[North Rhine-Westphalia]], on the border with [[Rhineland-Palatinate]]. Spanning an area of more {{cvt|141.2|km2|0}} on both sides of the river [[Rhine]], almost three-quarters of the city lies on the river's left bank.

To the south and to the west, Bonn borders the [[Eifel]] region which encompasses the [[Rhineland Nature Park]]. To the north, Bonn borders the [[Cologne Lowland]]. Natural borders are constituted by the river [[Sieg (river)|Sieg]] to the north-east and by the [[Siebengebirge]] (also known as the Seven Hills) to the east. The largest extension of the city in north–south dimensions is {{cvt|15|km|0}} and {{cvt|12.5|km|0}} in west–east dimensions. The city borders have a total length of {{cvt|61|km|0}}. The geographical centre of Bonn is the Bundeskanzlerplatz ''(Chancellor Square)'' in Bonn-Gronau.

=== Administration ===
The [[States of Germany|German state]] of [[North Rhine-Westphalia]] is divided into five [[Regierungsbezirk|governmental districts]] ({{langx|de|link=no|Regierungsbezirk}}), and Bonn is part of the [[Regierungsbezirk Köln|governmental district of Cologne]] ({{langx|de|link=no|Regierungsbezirk Köln}}). Within this governmental district, the city of Bonn is an [[List of districts of Germany|urban district]] in its own right. The urban district of Bonn is then again divided into four administrative municipal districts ({{langx|de|link=no|Stadtbezirk}}). These are Bonn, Bonn-Bad Godesberg, Bonn-Beuel and Bonn-Hardtberg. In 1969, the independent towns of [[Bad Godesberg]] and Beuel as well as several villages were incorporated into Bonn, resulting in a city more than twice as large as before.
