Johannes Rudolf Roth (September 4, 1815 – June 26, 1858) was a German zoologist and traveler.
Roth was born in Nuremberg to Karl Johann Friedrich von Roth, president of the Bavarian Supreme Consistory (Oberkonsistorialpräsident).
The younger Roth studied medicine and natural sciences, and in 1836–37 accompanied Gotthilf Heinrich von Schubert on his expedition to Egypt and Palestine.
Beginning in 1839 he traveled to the East Indies and the northwest coast of Africa.
