This thesis is devoted to the study of the representation theory of orthosymplectic superalgebras and their applications to physical theories. Techniques are developed to educe typical and atypical finite-dimensional, irreducible representations of orthosymplectic superalgebras. These include superfield and weight space procedures which are illustrated for several low-rank orthosymplectic superalgebras. Young supertableaux are used to enumerate finite-dimensional typical, tensor representations and spinor representations of OSp(M/N), and atypical, tensor representations of OSp(2/2), OSp(3/2) and OSp(4/2). Relations between Kac-Dynkin and supertableau labels are obtained and used to present conditions on diagram shape, necessary and sufficient for atypicality. Modification rules for typical supertableaux of OSp(M/N), and for atypical supertableaux of OSp(2/2), OSp(3/2) and OSp(4/2) are presented. Dimension formulae, in diagram notation, are discussed for typical, representations of OSp(M/N). New superfield realisations are presented for the determination of infinite-dimensional irreducible representations of N-extended super-Poincare algebras with central charges. These are illustrated for the N=2 extended super-Poincare algebra with one central charge. Finally, a discussion of the roles played by orthosymplectic supergroups in some physical theories is presented.
