It's Kathy Griffin who's been cut off ... by CNN, because she was just fired by the network, which means she will not ring in 2018 with Anderson Cooper.

The network is reacting to the photo of Kathy holding a bloody, beheaded image of Donald Trump. Her apology clearly wasn't enough for CNN.

As we reported, Anderson Cooper also lashed out at his former co-host and friend, saying, "For the record, I am appalled by the photo shoot Kathy Griffin took part in. It is clearly disgusting and completely inappropriate."

Griffin did the New Year's Eve special since 2007.
