We consider a curve $α=α(s)$ in Minkowski 3-space E₁³ and denote by ,N,B the Frenet frame of $α$. We say that $α$ is a slant helix if there exists a fixed direction U of E₁³ such that the function $$ is constant. In this work we give characterizations of slant helices in terms of the curvature and torsion of $α$.
