We construct a perfect lattice action for staggered fermions by blocki
ng from the continuum. The locality, spectrum and pressure of such per
fect staggered fermions are discussed, We also derive a consistent fix
ed point action for free gauge fields and discuss its locality as well
as the resulting static quark-antiquark potential, This provides a ba
sis for the construction of (classically) perfect lattice actions for
QCD using staggered fermions. (C) 1997 Elsevier Science B.V.
