UFC 7: The Brawl in Buffalo was a mixed martial arts event held by the Ultimate Fighting Championship on September 8, 1995, at the Memorial Auditorium in Buffalo, New York. The event was seen live on pay per view in the United States, and later released on home video.

UFC 7 featured an eight-man tournament, a UFC Superfight Championship match between reigning UFC Champion Ken Shamrock and UFC 6 tournament winner Oleg Taktarov, and three alternate fights, which were not shown on the live pay-per-view broadcast. The tournament had no weight classes, or weight limits. Each match had no rounds, but a 20 minute time limit was imposed for the quarterfinal and semi-final round matches in the tournament. The finals of the tournament and the Superfight had a 30 minute time limit and, if necessary, a five minute overtime.

Consistent with early UFC events, the time limit was not followed as the Superfight only featured a three minute overtime, perhaps due to pay-per-view time constraints. Regardless of this, the show ran over its three hour pay-per-view slot, cutting off some viewers from seeing the final match. The referee for the main card was 'Big' John McCarthy. Michael Buffer served as the guest ring announcer for the night.

Marco Antônio de Lima Ruas (Portuguese pronunciation: [ˈmaʁku ˈʁuɐs]; born January 23, 1961) is a retired mixed martial arts fighter and instructor. Most notably, he was the UFC 7 Tournament Champion and is considered one of the earliest examples of the complete mixed martial artist, highly skilled in both striking and grappling.

Ruas is famous for being the founder of Ruas Vale Tudo, a hybrid of Brazilian submission fighting and kickboxing. He also used to train in the art of capoeira with renowned Mestre Camisa in Rio de Janeiro at the Santa Luzia club, downtown Rio. He has instructed fighters such as Pedro Rizzo and Renato Sobral.

Some would regard him as one of the earliest pioneers of the now established MMA paradigm of a complete fighter - being able to strike, takedown and finish with submissions as his UFC 7 record indicates.

Ruas competed in early Ultimate Fighting Championship events, winning UFC 7 in a classic fight against 6'8", 330 lb Paul Varelans. He also faced down opponent Oleg Taktarov in UFC's Ultimate Ultimate, but lost via unanimous decision. Ruas would go on to a draw with Taktarov a year later, winning the WVC Super Fight belt in the process. He returned briefly to fight former heavyweight champion Maurice Smith in UFC 21, but lost by TKO. Ruas suffered an injury in the first round and could not continue.
