New Market, as it was originally known, and later also known as Head House (or Headhouse) Market and Second Street Market, is an historic street market which is located on South 2nd Street between Pine and Lombard Streets in the Society Hill neighborhood of Philadelphia, Pennsylvania. With a history dating to 1745, it is one of the oldest surviving market buildings of its type in the nation.

This portion, which survives from a longer structure originally extending all the way to South Street, was designated a National Historic Landmark in 1966, and is the centerpiece of the Head House Square historic district.
