Konstantinos Lagoumitzis ({{langx|el|Κωνσταντίνος Λαγουμιτζής}}, c. 1781–1851) was a Greek revolutionary during the Greek War of Independence (1821–1830), famous for his ability to dig tunnels during sieges.

Lagoumitzis was born in the village of Hormovo, in modern Albania, then part of the Ottoman Empire; though, his family was originally from the village of Lekli.{{harvnb|Pappa|2009|pp=249–250}} His real surname was either Papakyriakos (Παπακυριάκος) or Dalaropoulos (Νταλαρόπουλος), but he was also called Hormovitis (Χορμοβίτης; from Hormovo). He is mainly known as Lagoumitzis (sapper) due to his successful ability to dig tunnels ({{langx|el|λαγούμια|lagoúmia}}) beneath the camps of enemies and blow them up.

His successes during the siege of Messolonghi and the siege of the Acropolis (1826–27), made him famous. During these sieges, Lagoumitzis successfully countermined the Turkish besiegers.

He died in Athens, in 1851; the Greek state paid for his funeral.{{Cite news |date=6 June 1851 |title=[Κώστας Λαγουμτζής (Υπονομοποιός)] |work=Αιών |issue=1166 |quote=Απεβίωσεν εν Αθήναις επί ψάθης και ετάφη δια δημοσίων εξόδων ο συνταγματάρχης Κώστας Λαγουμτζής (Υπονομοποιός), ένας εκ των ωφελιμωτέρων αγωνιστών υπέρ της ανεξαρτησίας της πατρίδος.{{nbsp}}...}}
