Gigglebiz is a children's television programme made in the UK. There have been two series, first broadcast on CBeebies, the BBC's younger children's channel, in 2009 and 2011.

The programme's star and creator is Justin Fletcher, who plays the chief characters in all the comic sketches. Some sketches are filmed in the studio; one regular external location is Portmeirion, used for the town of Wiggyville where the Captain Adorable sketches are set. The sketches are interspersed with 'Giggle Box' - film segments of children viewers telling Justin jokes.

The first series was broadcast in September 2009 and comprised 25 15-minute episodes. The second series of 15 episodes was shown in January 2011. The new series saw some characters disappear to make way for new ones.
