Carl Georg Christoph Beseler (2 November 1809 in Rödemis, now part of Husum – 28 August 1888 in Bad Harzburg) was a Prussian jurist and politician.

He was forbidden to teach law in Kiel in 1833 due to his political activity, but he lectured at Göttingen and Heidelberg.

[1] A liberal nationalist, Beseler was a member of the Frankfurt Parliament where he participated in writing the failed 1849 German constitution.

From 1849 to 1852 and from 1857 to 1887 he was a member of the Prussian House of Lords, 1850 of the Erfurt Union Parliament and 1874 to 1877 of the Reichstag.

As a notable "Germanist" opponent of the "Romanists", led by Friedrich Carl von Savigny, Beseler advocated a "people's law" based on Germanic principles as opposed to the Romanists' "jurists' law".
