A relativistic string is usually represented by the Nambu-Goto action in terms of the extremal area of a two-dimensional timelike submanifold of Minkowski space. Alternatively, a family of classical solutions of the string equation of motion can be globally described in terms of the associated geodesic field. In this paper we propose a new gauge theory for the geodesic field of closed and open strings. Our approach solves the technical and conceptual problems affecting previous attempts to describe strings in terms of local field variables. The connection between the geodesic field, the string current, and the Kalb-Ramond gauge potential is discussed and clarified. A non-Abelian generalization and the generally covariant form of the model are also discussed.
