Johann Georg Graevius (originally Grava or Greffe; 29 January 1632 – 11 January 1703) was a German classical scholar and critic. He was born in Naumburg, in the Electorate of Saxony. Graevius was originally intended for the law, but made the acquaintance of Johann Friedrich Gronovius during a casual visit to Deventer, under whose influence he abandoned jurisprudence for philology. He completed his studies under Daniel Heinsius at Leiden, and among others under the Protestant theologian David Blondel at Amsterdam. Graevius died in Utrecht in 1703.
