Johann Georg Edlinger was an Austrian portrait painter.

Edlinger was born at Graz in 1741. He was a pupil of Desmarées, and became court painter at Munich, where he died in 1819. His portraits are well painted, and show a leaning towards the works of Rembrandt. Some of his portraits of eminent Bavarians, engraved by Friedrich John, appeared in 1821 under the title Sammlung von Bildnissen denkwürdiger Männer.
