Atheistic agnosticism is the belief that the knowledge of a god or gods is unknowable. While athiests carry the belief that there is no god, and thiests hold that there is a god, atheistic agnostics ackowledge that while there is no possible way to prove that there is a god, that absence of proof does not necesarily mean that there isn't one.

Atheistic agnosticism is not to be confused with theistic agnosticism, which states that there is a god, but his nature or character is unknowable.
