Count Georg Magnus Sprengtporten was a Finland-Swedish politician, younger brother of Jacob Magnus Sprengtporten. Since he defected to Russia, he went down in Swedish history as a traitor.

Baron Jacob Magnus Sprengtporten (1727–1786) was a Swedish-Finnish army officer and politician, and half-brother of Georg Magnus Sprengtporten. He is most famous as one of the leaders of the Revolution of 1772, the coup d'état which ended the age of constitutional monarchy in Sweden known as the Age of Liberty and ushered in the period of absolute monarchy known as the Gustavian era.
