Colonel Sponsz is a fictional character from The Adventures of Tintin series of classic comic books written and drawn by Hergé. He is a veteran spymaster and an enemy of the main protagonists.

The monocle-wearing Sponsz is a native of the nation of Borduria, where he became the Chief of Police of the capital Szohôd, and the head of the Secret Police or ZEP, which operates on behalf of the country's dictator Marshal Kurvi-Tasch. He is a calculating and ruthless figure, and bears strong grudges against those who upset his political machinations.
