The Chaos Pool was the 119th monthly Doctor Who audio story produced by Big Finish Productions. It was the third and final title in The Key 2 Time audio trilogy.

The story is notable for several reasons surrounding guest star Lalla Ward. This is the only piece of performed Doctor Who where she appears as both Romana II and Astra of Atrios. It's also the only time Romana II has an audio encounter with the Fifth Doctor.
