Abstract.
These are the lecture notes from the 26th Winter School ``Geometry and Physics", Czech Republic, Srn\'{\i}, January 14 -- 21, 2006. These lectures are an introduction into the realm of generalized geometry based on the
tangent plus the cotangent bundle. In particular we discuss the relation of this geometry to physics, namely to
two-dimensional field theories. We explain in detail the relation between generalized complex geometry and supersymmetry. We briefly review the generalized K\"ahler and generalized Calabi-Yau manifolds and explain their
appearance in physics.
