Johann Konrad von Gemmingen (also Conrad) (1561−1612) was Prince bishop of Roman Catholic Diocese of Eichstätt in Bavaria.

His uncle, the Augsburg Prince-Bishop Otto von Gemmingen, is said to have had a significant influence on his upbringing and repeatedly appears as his mentor.

[1][2] In 1579 he began his higher education, studying theology and then law at the University of Freiburg in Breisgau in 1583 in Dillingen, 1584 in Pont-à-Mousson, 1587 in Paris, 1588 in Siena, 1588/89 in Perugia and 1589 in Bologna.

In 1594 Pope Clement VIII appointed him titular bishop of Hierapolis in Isauria and Emperor Rudolf II bestowed the regalia on him.

[1][2] On 17 September 1594 Johann Konrad von Gemmingen assumed control of the Bishopric of Eichstätt while at the same time vacating his Augsburg Cathedral Deanery.

On the death of the reigning bishop, Kaspar von Seckendorff on 2 April 1595 he assumed the full bishopric and was consecrated on 2 July 1595.

[2] In modern times, the bishop is known mainly for the Eichstätt Garden (Eichstätter Garten or Hortus Eystettensis) that he commissioned, which was laid out over eight terraces, facing the castle hill towards the city.

He invested almost 20,000 guilders in this project, which resulted in a work of art that is still famous and coveted today as the most modern and most comprehensive plant book (florilegium) of all time.

[2] The family chronicle of the Lords of Gemmingen describes the tomb as follows: His corpse covers the most beautiful monument among the bishops of Eichstädt, which Christoph v. Westerstetten set.
