Janko Katić (; fl. 1795–1806†) was a Serbian voivode and one of the organizers of the First Serbian Uprising (1804–1813). He participated in the uprising since day one, and was an important "oborknez" of the Šabac district, and was one of the most courageous commanders, so influential as a military and political leader that he was held by many as the second only to Karađorđe Petrović, the leader, in Šumadija.
