Action Blast! was an animation television program shown on the American cable and satellite channel, G4 in the 8am ET hour. Hosted by Louden Noxious and The Beav from Kaiju Big Battel, the show was premiered on January 2, 2006 and ended exactly one year later on January 1, 2007.

The program was not produced by G4; instead the entire hour was programmed and produced by toymaker Hasbro, with the company buying paid programming time from G4, and none of the network's logo, bugs, or promotions were seen on the program except for one promo ad on the half-hour. An Action Blast! bug was formerly seen on the bottom left-hand corner but later replaced with another alternate name for the block, MonkeyBarTV.

Action Blast! was accused of violating a license stating that only Cartoon Network and Kids WB! have the rights to air Transformers Cybertron and Battle B-Daman.
