Rhine-Neckar
polycentric metropolitan region located in south western Germany

The Rhine-Neckar Metropolitan Region (German: Metropolregion Rhein-Neckar, pronounced [metʁoˈpoːlʁeˌɡi̯oːn ˌʁaɪnˈnɛkaʁ]), often referred to as the Rhein-Neckar Triangle, is a polycentric metropolitan region located in south western Germany, between the Frankfurt/Rhine-Main region to the north and the Stuttgart Region to the south-east.
Rhine-Neckar has a population of some 2.4 million, with major cities including Mannheim, Ludwigshafen and Heidelberg. Other cities include the former free imperial cities of Speyer and Worms. The metro area also encompasses parts of the Baden and Palatinate wine regions, the second largest vine region of the country (Deutsche Weinstraße), and territory from the three federal states of Baden-Württemberg, Rhineland-Palatinate and Hesse. It has a strong local identity as a successor to the historical Electorate of the Palatinate state.
The region is named after the rivers Rhine and Neckar, which join at Mannheim. Since 2005, the region has been officially recognized as a European Metropolitan Area.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
