Let Mn,d be the moduli space of semi‐stable rank n , trace‐free Higgs bundles with fixed determinant of degree d on a Riemann surface of genus at least 3. We determine the following automorphism groups of Mn,d : (i) the group of automorphisms as a complex analytic variety, (ii) the group of holomorphic symplectomorphisms, (iii) the group of Kähler isomorphisms, (iv) the group of hypercomplex automorphisms, (v) the group ofhyper‐Kähler isomorphisms. When n and d are coprime we show that Mn,d admits an anti‐holomorphic isomorphism if and only if the corresponding Riemann surface admits such a map. We then use this to determine the isometry group of Mn,d .
