Stefan Nemanjić (around 1165 – September 24, 1228) is Grand Prince of Serbia from 1196, and the King of Serbia from 1217 until his death in 1228.

He is the first official Serb King, and through his promotion of the Serbian Grand Principality into a kingdom and helping his brother Saint Sava in establishing the Serbian Church, he is regarded as one of the most important of the long lasting Nemanjić dynasty.

Stefan's literary opus is modest but of high quality.

He writes "The Life of Stefan Nemanja," a biography of his father.
