Covariant actions for N=1, D=6 Supergravity theories with chiral bosons

We show that the recently found covariant formulation for chiral $p$--forms in $2(p+1)$ dimensions with $p$ even, can be naturally extended to supersymmetric theories. We present the general method for writing covariant actions for chiral bosons and construct, in particular, in six dimensions covariant actions for one tensor supermultiplet, for pure supergravity and for supergravity coupled to an arbitrary number of tensor supermultiplets.
