Abstract
It is pointed out that hybrid inflation can be implemented with the in flaton field rolling away from the origin instead of towards it. This ''inverted'' hybrid inflation has a spectral index n<1, in contrast wi th ordinary hybrid inflation which has n greater than or similar to 1, so a measured value of n substantially different from 1 would disting uish the two. Other generalizations of hybrid inflation are also consi dered.
