Marks (Russian: Маркс), also spelled Marx, named after Karl Marx, is a town in Saratov Oblast, Russia, located 60 kilometers (37 mi) northeast of Saratov, the administrative center of the oblast.

[3] It was founded in 1767 as a Volga German community called Baronsk (Баронск), named so because the Dutchman Ferdinand Baron Caneau de Beauregard, who was a baron, founded the city.

[13] It was soon renamed Katharinenstadt (Екатериненштадт; Yekaterinenshtadt, Jekaterinenstadt; 1915 - 1920 Yekaterinograd), after Catherine the Great.

In 1918, it was granted town status and was the location for the administration of the Labour Commune of Volga Germans.

[citation needed] As a municipal division, Marks Town Under Oblast Jurisdiction is incorporated within Marksovsky Municipal District as Marks Urban Settlement.
