Hieronymus Bock (Latinised Hieronymus Tragus; c. 1498 – 21 February 1554) was a German botanist, physician, and Lutheran minister who began the transition from medieval botany to the modern scientific worldview by arranging plants by their relation or resemblance.

He became the prince's physician and caretaker of the kitchen garden of the count palatine and in 1533 received a life-time position as a Lutheran minister in nearby Hornbach where he stayed up to his death in 1554.

His surname was translated into Latin as Tragus; Bock is German for "male goat," while τράγος (tragos) is Ancient Greek for the same.

In the wine world, Bock is noted for having the first documented use of the modern word Riesling in 1552 when it was mentioned in his Latin herbal.
