  We explore the role that red giants might play in the central regions of
Active Galactic Nuclei. Due to their large radii and the low binding energy of
the stellar envelope, giants are vulnerable to envelope stripping from
collisions with the accretion disk. Using hydrodynamic simulations we show that
such collisions will typically deposit a substantial fraction of the envelope
mass into the disk on each passage. Repeated encounters will then lead to the
complete destruction of the star save for the dense core. We estimate the rate
of fuel supply by this mechanism using simple models for the AGN disk and
central stellar cluster. If the central stellar density is of order 10^7 solar
masses per cubic pc, then stripping of giants could account for the activity of
typical AGN provided that the accretion disk extends beyond 0.1 pc. For AGN
with smaller disks, or clusters of lower central density, giant stripping could
be an important source of gas enriched via stellar nucleosynthesis.
