The Nord-Sud Company (English: North-South; French: Société du chemin de fer électrique souterrain Nord-Sud de Paris) was an operator of underground trains in Paris established in 1904, which built two lines, Line A (now Line 12) and Line B (now part of Line 13) and had a concession to build a third. It was taken over by the Compagnie du chemin de fer métropolitain de Paris (CMP) in 1930 and incorporated into the Paris Métro.
