We review the construction of extended ( N=2 and N=4 ) superconformalalgebras over triple systems and the gauged WZW models invariant under them.The N=2 superconformal algebras (SCA) realized over Freudenthal triple systems(FTS) admit extension to ``maximal'' N=4 SCA's with SU(2)XSU(2)XU(1) symmetry.A detailed study of the construction and classification of N=2 and N=4 SCA'sover Freudenthal triple systems is given. We conclude with a study andclassification of gauged WZW models with N=4 superconformal symmetry.Comment: Invited talk presented at the Gursey Memorial Conference I in  Istanbul, Turkiye (June 6-10, 1994). To appear in the proceedings of the  conference. (21 pages. Latex document.
