Vale-tudo (Portuguese for anything goes) describes competitions in unarmed combat having minimal rules, especially up until the modern day mixed martial arts competitions. It is sometimes also considered a combat sport and style of fighting in itself.

The term vale tudo comes from the name of a television show that aired in Brazil starting in the 1960's. The show was a telecast of style-versus-style fights hosted by Hélio Gracie, which later changed into a Brazilian Jiu-Jitsu tournament followed by the victor fighting an invited opponent of another style in a vale tudo bout. Vale Tudo is also the name of a 2006 feature movie by director Alexander Pickl. Produced by Oliver Jahr and Gabor Harrach it tells the stories of underground fighters in Miami. Vale tudo is basically a hybrid of Jiujitsu, Brazilian Jiujitsu, Boxing, Wrestling and Muay Thai that was all brought to Brazil.
