Viktor Karl Jakob von Maydell (28 August 1838 – 27 January 1898), Baron von Maydell, was a Baltic German railway engineer and politician who was the mayor of Reval (now Tallinn) from December 1885 to July 1894.

In Zürich, he was one of the founders of the Corps Baltica-Borussia Danzig zu Bielefeld.

He then settled back in his native Estonia, where he bought the Gut Wiems in Reval.

For a few months before his mayoralty, he was the deputy mayor after the forced resignation of Wilhelm Greiffenhagen.

For health reasons, he left Reval and settled with his family in Stuttgart, where he died in January 1898.
