Let X be a smooth complex projective curve, and let xXx∈X be a point. We compute the automorphism group of the moduli space of framed vector bundles on X of rank r2r≥2 with a framing over x. It is shown that this automorphism group is generated by the following three: (1) pullbacks using automorphisms of the curve X that fix the marked point x, (2) tensorization with certain line bundles over X and (3) the action of PGLr(C)PGLr(C) through composition with the framing.
