Abstract: Given a non-singular variety with a K3 fibration $\pi\colon X\to S$we construct dual fibrations $\Hat{\pi}\colon Y\to S$ by replacing each fibre $X_s$ of $\pi$ by a two-dimensional moduli space of stable sheaves on $X_s$. In certain cases we prove that the resulting scheme $Y$ is a non-singular variety and construct an equivalence of derived categories of coherent sheaves $\Phi\colon \operatorname{D}(Y)\to \operatorname{D}(X)$. Our methods also apply to elliptic and abelian surface fibrations. As an application we use the equivalences $\Phi$ to relate moduli spaces of stable bundles on elliptic threefolds to Hilbert schemes of curves.
