  We investigate Poisson-Lie symmetry for T-dual sigma models on supermanifolds
in general and on Lie supergroups in particular. We show that the integrability
condition on this super Poisson-Lie symmetry is equivalent to the super Jacobi
identities of the Lie super-bialgebras. As examples we consider models related
to four dimensional Lie super-bialgebras $((2A1,1 + 2A)^1, D10_p=1/2)$ and
$((2A1,1 + 2A)^1, I)$. Then generally it is shown that for Abelian case (g, I)
the super Poisson-Lie T-duality transforms the role of fermionic (bosonic)
fields in the model to bosonic (fermionic) fields on the dual model and vice
versa.
