桑巴（葡萄牙语：Samba），是源于巴西巴伊亚的一种舞蹈和音乐类型。桑巴最早根源于非洲土着带有宗教仪式性的舞蹈，通过被贩卖到巴西的黑人奴隶带到巴西，再与流传至当地的其他文化混合，渐渐反演成今日的桑巴。桑巴现已被世界公认为巴西和巴西狂欢节的象征。桑巴被认为是最大众化的巴西文化表达形式之一，已经变成巴西国家认同的符号。巴伊亚的圆圈桑巴舞（一种里约热内卢的桑巴）在2005年被联合国教科文组织列入人类非物质文化遗产代表作名录。

桑巴原是非洲土着舞蹈，原是一种带有宗教仪式性的舞蹈。在16至18世纪间，葡萄牙人由非洲如安哥拉、刚果等地引进了大量黑奴至殖民地巴西，以取代巴西人与原住民不愿做的工作，而黑奴也将他们的舞蹈带入巴西。

Samba (Portuguese pronunciation: [ˈsɐ̃bɐ]) is a Brazilian musical genre and dance style, with its roots in Africa via the West African slave trade and African religious traditions, particularly of Angola and the Congo, through the samba de roda genre of the northeastern state of Bahia, from which it derived. Although there were various forms of samba in Brazil in the form of various popular rhythms and regional dances that originated from drumming, samba as a music genre is seen as originally a musical expression of urban Rio de Janeiro, then the capital and largest city of Imperial Brazil.
