We use the expansion of superalgebras procedure (summarized in the text) toderive Chern-Simons (CS) actions for the (p,q)-Poincare supergravities inthree-dimensional spacetime. After deriving the action for the (p,0)-Poincaresupergravity as a CS theory for the expansion osp(p|2;R)(2,1) of osp(p|2;R), wefind the general (p,q)-Poincare superalgebras and their associated D=3supergravity actions as CS gauge theories from an expansion of the simpleosp(p+q|2,R) superalgebras, namely osp(p+q|2,R)(2,1,2).
