5Shake! is a British free-to-air children's television channel owned by Channel 5 Broadcasting Ltd, ultimately owned by ViacomCBS Networks UK & Australia.
In November 2008, Channel 5 had been set to launch a new children's channel based on its pre-school programming block. This was a response to the BBC launching the CBBC channel and CBeebies in 2002 and ITV launching the CITV channel in 2006, but plans to launch a standalone children's channel were put on hold while the broadcaster awaited a buyer.
On 6 July 2020, the channel was announced at the Children's Media Conference, tentatively without a name. The channel was eventually named 5Shake! and was launched on 15 August 2020.
