Bad Girls Club (abbreviated BGC) is a 2006 American reality television series created by Jonathan Murray for the Oxygen network in the United States. The show focused on the altercations and physical confrontations of seven aggressive, quarrelsome, unruly women. They were featured on the show as "charismatic tough chicks." The cast, deemed "bad girls," enjoyed a luxurious lifestyle in a mansion for three months, during which they obeyed specified rules. Their lives inside and outside the house were recorded by a production team.

Bad Girls Club aired on at least seven networks in other countries: Sky Living in the United Kingdom and Ireland, MTV in Australia, New Zealand and Russia, RTL 5 in the Netherlands, TV11 in Sweden, SIC Radical in Portugal, Velvet in the Philippines, and Channel [V] in Southeast Asia. If a cast member violated production rules, she was evicted from the show and often replaced. The fourth season was the series' "breakthrough season" as Oxygen's first series to average over one million viewers per episode.There were four spin-offs, including Bad Girls Road Trip, Tanisha Gets Married, Love Games: Bad Girls Need Love Too, and Bad Girls All-Star Battle. In late 2016, Bad Girls Club was renewed for a 17th season, Bad Girls Club: East Meets West. In February 2017, the series' future was put in limbo with the network's announcement that it would convert to a true crime programming format, which was instituted in July 2017. Of the series' future, NBCUniversal Cable Entertainment Lifestyle Networks president Frances Berwick said, "Bad Girls Club, at this stage, I don't see it on Oxygen linear," suggesting that it could air in a non-linear media form. "Beyond that, we haven't figured it out yet."
