Abstract.A new form of contra-continuity, called weak contra-continuity, is introduced and used to investigate S-closed spaces and strongly S-closed spaces. It is shown that weak contra-continuity is strictly between contra-continuity and slight continuity. Also the basic properties of weakly contra-continuous functions are developed.
