This paper concerns on the existence of Sasakian or K-contact structures on Smale-Barden manifolds. Many interesting examples with different properties are presented, including a Sasakian quasi-regular but not Sasakian semi-regular Smale-Barden manifold and a quasi-regular Sasakian but not K-contact semi-regular Smale-Barden manifold. The authors also classified the Smale-Barden manifolds with null Sasakian structures.
