Midget wrestling is professional wrestling involving people of exceptionally short stature. Its heyday was in the 1950s and 1960s, when wrestlers such as Little Beaver, Lord Littlebrook, toured North America, and Sky Low Low was the first holder of the National Wrestling Alliance's World Midget Championship. In the following couple of decades, more wrestlers became prominent in North America, including foreign wrestlers like Japan's Little Tokyo.

The attraction was very popular in wrestling promotions from the 1950s into the 1970s. Many cards included midget wrestlers and included tag team and women's midget wrestling. Television shows for promotions in various cities frequently included midget matches.

Midget wrestling began to wane after WWF's WrestleMania III. Afterward, promotions continued to feature midget divisions, but its popularity was slowly declining. By the mid-1990s, midget wrestlers mostly appeared in comical matches and segments, rather than serious competitive wrestling-type matches. In Mexico, this was not the case, as wrestler Mascarita Sagrada continued to compete in prominent Mexican promotions such as AAA and Consejo Mundial de Lucha Libre. By the mid-2000s in the United States, midget divisions once again were part of major wrestling promotions, and wrestlers such as WWE's Hornswoggle were competing for and winning championships made for average-size male wrestlers.

The Little People of America (LPA) have criticized midget wrestling as reinforcing stereotypes that little people are no more than entertainment, and the use of the word "midget", stating that it is as offensive as a slur. Opinions on the term from performers competing in the events is mixed; some consider the term merely descriptive of their small size, and others considering it outdated or offensive.

Midget professional wrestling had its early origins in the vaudeville shows of the United States. In these shows, comedy was as important as athletics. The sport is also indebted to professional wrestling's carny origins, where a premium was placed on the visually unusual.

In 1949, Sky Low Low won a thirty-man battle royal to become the winner of the first NWA World Midget Championship, a singles midget championship promoted by the National Wrestling Alliance. Sky Low Low, one of the most prominent midget professional wrestlers, had a longtime feud with Farmer Brooks.

The 1950s have been called the "golden age of midget wrestling". During the decade, Sky Low Low, Little Beaver, Lord Littlebrook, and Fuzzy Cupid all toured the territories of Canada, wrestling in promotions such as Stu Hart's Stampede Wrestling. The dominant promoter and booker for midget wrestling at the time was Jack Britton, who was stationed in Montreal, Quebec. In Ontario, Larry Kasaboski also promoted midget wrestling shows. In Canada, Sky Low Low and Little Beaver earned up to 15% of the gate proceeds at their events.

The midget professional wrestlers had many gimmicks to attract audiences and revenue. One of Sky Low Low's gimmicks was an open challenge to any other midget professional wrestlers to beat him in a two out of three falls match for $100. He often turned himself upside down and balanced on his head. The duo of Sky Low Low and Little Beaver even squared off in a match for Elizabeth II and King Farouk of Egypt. Sky Low Low also frequently teamed with Fuzzy Cupid in tag team matches. Meanwhile, Lord Littlebrook was credited as being one of the first wrestlers of any height to use aerial maneuvers in his matches. In addition to North America, Littlebrook wrestled in Australia, Japan, and Thailand. The midget wrestlers also performed in Cuba (prior to 1959), South America, Central America, England, Ireland, Scotland, and the countries on the mainland European continent.
