Kyriakoulis Mavromichalis (Greek: Κυριακούλης Μαυρομιχάλης; 1765–1822) was a Greek revolutionary who fought in the Greek War of Independence. He was born in Limeni in the Mani Peninsula, the son of Pierros Pierrakos and Katerina Koutsogrigorakos and was the young brother of Petrobey Mavromichalis. When the Greek War of Independence broke out he organised a band of young Maniots into a fighting force. Kyriakoulis fought at Kalamata, Methoni, Koroni and was present at the Siege of Tripolitsa operation as commander-in-charge of the Valtetsi headquarters in the incipient revolutionary army.
