Brandenburg an der Havel is a town in Brandenburg, Germany, which served as the capital of the Margraviate of Brandenburg until replaced by Berlin in 1417.
With a population of 71,778 (as of 2010), it is located on the banks of the River Havel. The town of Brandenburg provided the name for the medieval Bishopric of Brandenburg, the Margraviate of Brandenburg, and the current state of Brandenburg. Today it is a small town compared to nearby Berlin, but it was the original nucleus of the former realms of Brandenburg and Prussia.

In front the Altstädtisches Rathaus (Old Town Hall), a late Gothic brick building with stepped gables and an ornate portal, stands a 5.35m high statue of the knight Roland. Made of sandstone, the statue was erected in 1474 as a symbol of the town's independence.
