  We introduce the notion of omni-Lie superalgebra as a super version of the
omni-Lie algebra introduced by Weinstein. This algebraic structure gives a
nontrivial example of Leibniz superalgebra and Lie 2-superalgebra. We prove
that there is a one-to-one correspondence between Dirac structures of the
omni-Lie superalgebra and Lie superalgebra structures on subspaces of a super
vector space.
