In this paper, we prove some fixed point theorems for contraction mappings in cone b-metric spaces. Dass-Gupta , Jaggi-Dass , Jaggi , M.S. Khan  and others proved theorems for different spaces using rational function and contraction conditions. Inspiring from above results, we proved theorems in cone b-metric spaces.
