Peter Johann Nepomuk Geiger (11 January 1805 – 29 October 1880) was a Viennese artist.

Born in Vienna, Geiger wanted originally to follow the family tradition and become a sculptor, but drawing and painting were his natural element.

Until 1848, he carried out numerous illustrations of historical works and poetry, but also made oil paintings for the Austrian Royal Family.

Returning from a journey to the Orient with Prince Ferdinand Maximilian Joseph in 1850, he entered a particularly creative period.

For the Royal Family, he made many works including illustrations of Goethe, Friedrich Schiller, and William Shakespeare.
