Aspecial manifold is an allowed target manifold for the vector multiplets ofD=4,N=2 supergravity. These manifolds are of interest for string theory because the moduli spaces of Calabi-Yau threefolds andc=9, (2, 2) conformal field theories are special. Previous work has given a local, coordinate-dependent characterization of special geometry. A global description of special geometries is given herein, and their properties are studied. A special manifold ℳ of complex dimensionn is characterized by the existence of a holomorphicSp(2n+2,R) ⊗GL(1,C) vector bundle over ℳ with a nowhere-vanishing holomorphic section Ω. The Kähler potential on ℳ is the logarithm of theSp(2n+2,R) invariant norm of Ω.
