  We study the effects of twisted boundary conditions on the quark fields in
the epsilon regime of chiral perturbation theory. We consider the
$SU(2)_L\times SU(2)_R$ chiral theory with non-degenerate quarks and the
$SU(3)_L\times SU(3)_R$ chiral theory with massless up and down quarks and
massive strange quarks. The partition function and condensate are derived for
each theory. Because flavor-neutral Goldstone bosons are unaffected by twisted
boundary conditions chiral symmetry is still restored in finite volumes. The
dependence of the condensate on the twisting parameters can be used to extract
the pion decay constant from simulations in the epsilon regime. The relative
contribution to the partition function from sectors of different topological
charge is numerically insensitive to twisted boundary conditions.
