## Abstract in another language

In this paper, we study the topology of the stack Tg of smooth trigonal curves of genus g over the complex field. We make use of a construction by the first named author and Vistoli, which describes Tg as a quotient stack of the complement of the discriminant. This allows us to use techniques developed by the second named author to give presentations of the orbifold fundamental group of Tg, and of its substrata with prescribed Maroni invariant, and describe their relation with the mapping class group Mapg of Riemann surfaces of genus g.
