Inspired by toric geometry, I explain how to associate a cone (in the sense of convex geometry) to an abelian category; a fan to a bounded heart; a multifan to a triangulated category. One motivation for doing this is a connection to stability conditions, and a related open cone construction provides a purely convex-geometric description of Bridgeland’s stability space.
