The squeezed superposition actes introduced in this paper are non--classical states of radiation field generated by using the superghtion stutds as input field of a squeezing system. These ststes behsve two squeezing mechanisms, the one is responsible.for the squeezing of Wigner space, the other is respollsible for the superposition of number saltes. The quantum statistical properties and squeezing of the squeezed superstition stutds are discussed.
