Abstract
In this paper we study the Weierstrass points of singular Gorenstein curves. We need to analyze separately the cases in which the trigonal pencil is induced by a line bundle or not, in which the Weierstrass point, $P$, is a smooth point or not, in which $P$ is a smooth ordinary or total ramification point or not.
