Carl Johan Adlercreutz (27 April 1757 – 21 August 1815) was a Swedish general and statesman, born in Borgå (Porvoo), Finland on family estates. Entering the Swedish army aged 13 in the Finnish Light Cavalry Brigade, he was present when Gustav III launched his coup-d’etat. He studied military theory in Stockholm.

In 1777 he joined the Savo Brigade guarding the Finnish border against Russian aggression. Adlercreutz first saw action in the 1788–1790 Russo-Swedish War, where he distinguished himself. He was promoted Major in 1791 and Squadron Commander 1792. During the Anjala conspiracy he remained faithful to the King, standing against the war with Russia, then took part in the trials against the conspirators. He was thereafter appointed the commanding officer of the Nyland Dragoons, holding this post until 1804, when he was made Ofverste (Colonel-in-Chief) of the newly raised Adlercreutz Regiment.
