Theodor von Rüdiger (Russian: Фёдор Васильевич Ридигер; 1783 in Mittau – 11 June 1856 in Saint Petersburg) was a German military officer in service of the Russian Empire and a general of the Imperial Russian Army.

Born in Mittau (now Jelgava), Courland to a family of local Baltic Germans, von Rüdiger graduated from a local college in Mittau and in 1799 he joined the Semenovsky Regiment of Life Guards. Throughout his career he served in a number of other units and occupied a number of posts, including Warrant Officer of the Sumy Hussar Regiment (1800) and adjutant to General Peter von der Pahlen (1801). During the Napoleonic Wars he took part in the Battle of Guttstadt-Deppen of 1806. Transferred to Grodno Hussar Regiment, he fought in Battle of Friedland of 1807. For his part in the war he was awarded the Order of St. Anna, 3rd Class.

Following the Treaties of Tilsit he took part in the Finnish War. Promoted to the rank of Major on 23 October 1807, he took part in the capture of Björneborg and Tavastehus. He led a small detachment pursuing the Swedish army all the way to the city of Vaasa and captured it, for which he received the Order of St. Vladimir, 4th class.
