Groß-Zimmern is a municipality in the district of Darmstadt-Dieburg, in Hessen, Germany.

It is situated 10 kilometres (6.2 mi) east of Darmstadt and right next to Dieburg.

In 1846, over 700 town residents emigrated in the Great Migration to New York City.

The emigrants sailed on at least five ships – the Atlas (46%), the Sardinia (37%), the Manchester (6%), the Montezuma (7%), and the Pontiac (6%).

New York City petitioned the US Congress to pass laws that would prevent the arrival of paupers on overcrowded ships to the United States.
