Smackgirl was a Japanese mixed martial arts promotion focused solely on female fighters.

The promotion also held grappling and amateur events along with its main line of professional MMA cards.

After financial difficulties throughout 2008 the promotion was sold to Marverous Japan Co., Ltd. and rebranded JEWELS.
