Boxers who weigh 200 pounds and over (14 st 3 lb, 90 kg) are considered heavyweights by the major professional boxing organizations: the International Boxing Federation, the World Boxing Association, the World Boxing Council, and the World Boxing Organization.
For most boxing organizations, the maximum weight for a cruiserweight is 200 pounds. Thus, a fighter whose weight is over 200 lb (14 st 3 lb, 90 kg) may not fight as anything but a heavyweight.
Joe Louis holds the record for most consecutive title defenses at this division, with 25 defenses of the Universal title. This is also the record for most consecutive title defenses in boxing history.
Because this division had no weight limit, it has been historically vaguely defined. In the 19th century, for example, many heavyweight champions weighed 170 pounds (12 st 2 lb, 77 kg) or less (although others weighed 200 pounds).
The first heavyweight champion under the Marquess of Queensberry rules was John L. Sullivan, known as "The Boston Strong Boy". He weighed around 200 pounds when in shape and was a bare-knuckle champion. He was defeated by Jim Corbett on September 7, 1892, in 21 rounds.
In 1920, the minimum weight for a heavyweight was set at 175 pounds (12 st 7 lb, 79 kg), which today is the light heavyweight division maximum. Since 1980, for most boxing organizations, the maximum weight for a cruiserweight has been 200 pounds.
Since the 1960s, the heavyweight title has become fractured amongst various sanctioning organizations, and so what was once known as the single "Heavyweight Champion", is now referred to as the "Undisputed Champion" as the one fighter that has defeated all the other titlists.

The heavyweight division in MMA generally groups fighters between 205 and 265 lb (93 and 120 kg).
Heavyweight is also the title of a documentary film that documented the fight camp of Fabricio Werdum when he became the UFC Heavyweight Champion. 
The term "world heavyweight" in modern wrestling generally refers to a champion wrestler who is seen as a prominent competitor, rather than an adherent to a particular weight class. The World Heavyweight Championship in wrestling is usually considered the main title in a given promotion. Prior to the wrestling industry publicly acknowledging the predetermined nature of the sport, a Heavyweight title was generally competed for by larger wrestlers while smaller wrestlers competed as (among other names and classifications) ""Junior Heavyweights" and "Light-Heavyweights".
The word "heavyweight" is sometimes used in other fields (e.g. politics) to denote a person who is especially powerful or influential. In this context, "big beast" has a similar meaning. Other boxing analogies include "punching above his [their] weight" to denote a person or entity (e.g. a country) whose influence is arguably greater than his/its basic attributes would suggest.
