We establish weak factorizations for a weighted Bergman space $$A^p_{\alpha }$$ , with $$1<p<\infty $$ , into two weighted Bergman spaces on the unit ball of $$\mathbb {C}^n$$ . To obtain this result, we characterize bounded Hankel forms on weighted Bergman spaces on the unit ball of $$\mathbb {C}^n$$ .
