In this article, we investigate the regular Smarandache curves constructed from the Frenet vectors of spacelike Salkowski curve with a timelike principal normal. In the first part of the study, literature research was conducted. In the second part, general information about the curve and spacelike Salkowski curve in Minkowski space are given. In the last
part, the Frenet apparatus of the Smarandache curves are calculated. We draw a graphic of the obtained Smarandache curves and some related results about Smarandache curves are given.
