In this paper, timelike-spacelike Mannheim partner curve couple was defined in Lorentzian space and the relations were given between the curvatures and torsions of these curves. Furthermore, for a given curve couple, the necassary and sufficient conditions were obtained to become timelike-spacelike Mannheim partner curve couple in .
Key words: Mannheim curves, Lorentzian space, curvature, torsion.
