Reeperbahn, Entertainment street in St. Pauli, Hamburg, Germany.

Reeperbahn is a street nearly one kilometer long in the St. Pauli district of Hamburg-Mitte, Germany, known for its music clubs, theaters, restaurants, and entertainment establishments. The street runs parallel to the Elbe River and connects several smaller side streets lined with shops and venues.

The name comes from the ropewalks where ship ropes were twisted; these were moved outside the city walls toward Altona in the 1620s, and the street was a ropewalk in the 17th and 18th centuries. In the early 1960s the Beatles played the Star-Club, Kaiserkeller, Top Ten and Indra here.

The street's name comes from the ropewalks (Reepschläger) that once stood here; the Große Freiheit side street was named because Catholics could practise their religion there when Protestant Hamburg forbade it. Since 2006 the Reeperbahn Festival has been held every September, alongside the Schlagermove in early July and the Harley Days.

Visitors reach the street on foot from St. Pauli station on the U3 metro line, a short walk from the main entrance. Most venues open in the late afternoon, with crowds building after dark.

The Beatles-Platz at the corner of Reeperbahn and Große Freiheit marks where the band played the Star-Club, Kaiserkeller, Top Ten and Indra in the early 1960s. John Lennon later said: "I might have been born in Liverpool – but I grew up in Hamburg".
