Letbe a connected reductive group oversuch thatis quasi-split, and letbe a parabolic subgroup. We introduce parahoric overconvergent cohomology groups with respect toQ, and prove a classicality theorem showing that the small slope parts of these groups coincide with those of classical cohomology. This allows the use of overconvergent cohomology at parahoric, rather than Iwahoric, level, and provides flexible lifting theorems that appear to be particularly well-adapted to arithmetic applications. WhenQis a Borel, we recover the usual theory of overconvergent cohomology, and our classicality theorem gives a stronger slope bound than in the existing literature. We use our theory to constructQ-parabolic eigenvarieties, which parametrisep-adic families of systems of Hecke eigenvalues that are finite slope atQ, but that allow infinite slope away fromQ.
