Bornheim is a district or Stadtteil of Frankfurt am Main, Germany, with approximately 25,861 inhabitants. It is part of the Ortsbezirk Innenstadt IV, and is subdivided into 5 Stadtbezirke.
In the past, Bornheim was called Das lustige Dorf ("The merry village"), because it was the red-light district of Frankfurt up to some 120 years ago. It still retains some of its lively charm and is said to be the younger crowd's hangout, next to Sachsenhausen. The main street of Bornheim is Berger Straße, a cosmopolitan boulevard with many bars, pubs and restaurants and two of Frankfurt's most traditional cider houses, Solzer and Zur Sonne. Holy Cross Church, known for its modernist architecture, is located in Bornheim.
Two underground lines (U4 and U7) go through Bornheim.
