Dimitris Koliopoulos Plapoutas () (May 15, 1786 – July 1865) was a Greek general who fought during the Greek War of Independence against the rule of the Ottoman Empire. He was born on in Paloumba, Arcadia, the son of Kollias Plapoutas, an Armatolos, being this the reason why Theodoros Kolokotronis referred to him simply as "Koliopoulos" (). In 1811, he left Paloumba for the Ionian Islands where he became an officer in the British army. In 1818, he joined the Filiki Eteria, which was planning to liberate Greece from Ottoman control.
