Wervicq-Sud (Dutch: Zuid-Wervik) is a commune in the Nord department in northern France. Wervicq-Sud is one of the oldest villages.

The town is separated from its Belgian sister town of Wervik by the Lys River.

Located 15 km north of Lille and 20 km south of Ypres.

The name appears in the form Viroviacum in the Antonine Itinerary and the Peutinger map in the 3rd century, so the settlement is old. It was here that the roman road from Tournai to Cassel crossed the Lys (a tributary of the Scheldt). It had a fortified post, of which traces are still visible. It was mentioned by Sanderus in his "Flandria illustrata" in the sixteenth century.

For centuries, it belonged to the Counts of Flanders, and thence to the French kings. In 1527 by the Treaty of Madrid it passed under the suzerainty of the Spanish empire.

Wervicq-Sud during the sixteenth century was the main centre of tobacco production in Europe. It was dependent on Spain until Louis XIV's conquest in 1667. A part of the main agglomeration situated on the left side of the river was a Belgian province and on the left side of the river, reattached to the French province of Flanders, it later become a part of the Nord department under the name Wervicq-Sud in 1790.

Martine Aubry (French pronunciation: [maʁtin obʁi]; née Delors; born 8 August 1950) is a French politician. She has been the First Secretary of the French Socialist Party (Parti Socialiste, or PS) since November 2008 and Mayor of Lille (Nord) since March 2001. Her father, Jacques Delors, served as Minister of Finance under President François Mitterrand and was also President of the European Commission.

Aubry joined the PS in 1974 and was appointed Minister of Labour by Prime Minister Édith Cresson in 1991, but lost her position in 1993 after the Right won the legislative elections. However, she became Minister of Social Affairs when Lionel Jospin was appointed Prime Minister in 1997. She is mostly known for having pushed the popular 35-hour workweek law, known as the "Loi Aubry", reducing the nominal length of the normal full-time working week from 39 to 35 hours, and the law that created the Couverture maladie universelle (Universal health care coverage).

Aubry stepped down from her Cabinet post in 2001 to be elected Mayor of Lille in place of Pierre Mauroy. Aubry subsequently lost her seat in the National Assembly in the general election of 2002. In March 2008, she was reelected Mayor of Lille, with 66.55% of the votes.
