We show that Weinberg's leading soft photon theorem in massless abelian gauge theories implies the existence of an infinite-dimensional large gauge symmetry which acts non-trivially on the null boundaries $${\mathscr I}^\pm$$ of $(d+2)$-dimensional Minkowski spacetime. These symmetries are parameterized by an arbitrary function $$\varepsilon(x)$$ of the $$d$$-dimensional celestial sphere living at $${\mathscr I}^\pm$$. This extends the previously established equivalence between Weinberg's leading soft theorem and asymptotic symmetries from four and higher even dimensions to all higher dimensions.
