We consider a class of multidimensional maps which naturally generalize the QRT map of the plane. Our 2n-dimensional maps are volume preserving and have n rational invariants, but we do not generally have a symplectic form. However, many specializations and reductions are integrable, some of which we present. Included in these are some new four-dimensional generalizations of the McMillan map.
