Eisenberg is a German surname that translates to “iron mountain” or “iron hill.” It is composed of two elements:

1. “Eisen” meaning “iron”
2. “Berg” meaning “mountain” or “hill”

The name likely originated as a topographic surname for someone who lived near an iron-rich hill or mountain. It could also have been an occupational name for iron miners or metalworkers.

Eisenberg is also the name of several places in Germany and Austria, which may have given rise to the surname for people from those locations.

Notable bearers include Jesse Eisenberg, an American actor known for his roles in “The Social Network” and “Zombieland.”
