M2, M-2, M.2 or M02 may refer to:
The M2 is a major highway in Johannesburg, South Africa. It is named the Francois Oberholzer Freeway. It runs just to the south of the Central Business District eastwards where it connects with the N3 (only a short segment goes to the west of the CBD). The north-south M1 intersects with the M2 just to the east of the CBD.
The M2 MSBS was the second French submarine-launched ballistic missile. In French, MSBS is the abbreviation for Mer-Sol Balistique Stratégique, or Sea-Ground Strategic Ballistic Missile. It has two stages. It was deployed on the Redoutable-class SNLEs (Sous-marin Nucléaire Lanceur d'Engins) (Device-launching Nuclear Submarine) or SSBNs from 1974 to 1978, replacing the M1 MSBS. The M2 was itself replaced by the M20 MSBS beginning in 1977.
