Aganlija (Serbian Cyrillic: Аганлија; fl. 1801–04) was an Ottoman janissary leader that defected and along with three other janissary leaders took control over the Sanjak of Smederevo in 1801. These renegade janissaries were known as the Dahije. Aganlija and his entourage was attacked during talks in Drlupa with Serbian rebel leader Karađorđe (April 1804). He was wounded in the foot. This was the first big success of the Serbian rebels, which encouraged the people and in short time spread the revolt to most of the nahiyas in the sanjak, as well as two nahiyas in the Sanjak of Zvornik.
