In this paper, we introduce a new homological notion related to biprojective Banach algebras, namely A^{**}-biprojective Banach algebras. We study the relation between this new notion and the other homological notions, such as amenability, pseudo-amenability and inner amenability. Also, we investigate this new notion on certain Banach algebras such as group algebras, Lipschitz algebras and triangular Banach algebras.
