社交舞，又称交谊舞或交际舞，是来源于西方的一种舞伴舞。

社交舞当前已经以社交形式和比赛形式出现在世界各地。包括简单易学的普通交谊舞（Social Dance，俗称“普交舞”）和按全世界统一竞技比赛标准要求的国际标准交谊舞（International Standard ballroom dance，俗称“国标舞”）。以比赛形式出现的国际标准交谊舞也叫体育舞蹈（参见体育舞蹈）。

目前的国际标准跳法，是在英国人跳法的基础上发展起来的，称为国际标准风格（International Style）。在美国，还流行着称为美国风格（American Style）的社交舞。

Ballroom dance is a set of partner dances, which are enjoyed both socially and competitively around the world. Because of its performance and entertainment aspects, ballroom dance is also widely enjoyed on stage, film, and television.

Ballroom dance may refer, at its widest definition, to almost any type of partner dancing as recreation. However, with the emergence of dancesport in modern times, the term has become narrower in scope, and traditionally refers to the five International Standard and five International Latin style dances (see dance categories below). The two styles, while differing in technique, rhythm and costumes, exemplify core elements of ballroom dancing such as control and cohesiveness. Developed in England, the two styles are now regulated by the World Dance Council (WDC) and the world dancesport federation. (Wdsf). In the United States, two additional variations are popular: American Smooth and American Rhythm, which combine elements of both traditional Latin and Ballroom dances.
