blood sport or bloodsport is a category of sport or entertainment that involves bloodshed. Common examples of the former include combat sports such as  cockfighting and dog fighting and some forms of hunting and fishing. Activities characterized as blood sports, but involving only human participants, include the Ancient Roman gladiatorial games.
Many online video-sharing websites such as
YouTube do not allow videos of animal bloodsports to be shown on the site. 
Limitations on blood sports have been enacted in much of the world. Certain blood sports remain legal under varying degrees of control in certain locations (e.g.,
bullfighting and cockfighting) but have declined in popularity elsewhere.  Proponents of blood sports are widely cited to believe that they are traditional within the culture.  Bullfighting aficionados, for example, do not regard bullfighting as a sport but as a cultural activity.  It is sometimes called a tragic  spectacle, because in many forms of the event, the bull is invariably killed and the bullfighter is always at risk of death.
Hunting and recreational fishing Animal rights and animal welfare advocates have extended the term blood sport to various types of hunting. Trophy hunting and fox hunting in particular have been disparaged as blood sports by those concerned about animal welfare, animal ethics and conservation.
Recreational fishing has sometimes been described as a blood sport by those within the recreation.
Blood sports have been a common theme in fiction. While
historical fiction depicts real-life sports such as gladiatorial games and jousting, speculative fiction, not least dystopic science fiction suggests variants of blood sports in a contemporary or future society. Some popular works themed on blood sports are , Battle Royale , The Hunger Games , The Running Man , The Long Walk , Fight Club , Death Race 2000 , Amores Perros , Bloodsport , and Danganronpa . Blood sports are also a common setting for video games ( The Most Dangerous Game , Unreal Tournament , etc.), making up much of the Street Fighter fighting game genre.
Developed science fiction universes such as
and Star Wars feature different blood sports.
