Rodenberg (German: [ˈʁoːdn̩ˌbɛʁk] ⓘ) is a town in the district of Schaumburg, in Lower Saxony, Germany.

The town of Rodenberg lies between the Deister, Süntel and Bückeberg ridges.

The first documented mention (as "Castrum Rodenbergum") dates back to the year 930, when the predecessors of the Counts of Schaumburg built a castle or a fortified tower here.

In 1250, Rodenberg was elevated to the status of "Freien Wickbold" (fortified and privileged settlement), and on April 4, 1615, it was granted town rights by Count Ernst zu Holstein and Schaumburg.

Saline and Gesundbrunnen in Rodenberg were generously funded before Landgrave Wilhelm IX.

The ecclesiastical administration followed suit, so that this part of Schaumburg - and thus also Rodenberg - belongs to the Evangelical Lutheran Church of Hanover.

In the years 1927 and 1928 homeland games were held at the castle for the (delayed) 300-year celebration of the city rights.

In 1990, on July 8, a large parade with historical elements took place to celebrate the 375-year city charter.
