The Boston Neck or Roxbury Neck was an isthmus, a narrow strip of land connecting the then-peninsular city of Boston to the mainland city of Roxbury (now a neighborhood of Boston). The surrounding area was gradually filled in as the city of Boston expanded in population (see History of Boston). The land formerly composing the neck is part of the neighborhood now known as the South End.
