Mixed-sex sports are individual and team sports whose participants are not of a single sex. In organised sports settings, rules usually dictate an equal number of people of each sex in a team. Usually, the main purpose of these rules are to account for physiological sex differences. Mixed-sex sports in informal settings are typically groups of neighbours, friends or family playing without regard to the sex of the participants. Mixed-sex play is also common in youth sports as before puberty and adolescence, sport-relevant sex differences affect performance far less.

Pair skating is a figure skating discipline defined by the International Skating Union (ISU) as "the skating of two persons in unison who perform their movements in such harmony with each other as to give the impression of genuine Pair Skating as compared with independent Single Skating". The ISU also states that a pairs team consists of "one Woman and one Man". Pair skating, along with men's and women's single skating, has been an Olympic discipline since figure skating, the oldest Winter Olympic sport, was introduced at the 1908 Summer Olympics in London. The ISU World Figure Skating Championships introduced pair skating in 1908.
