Lund University Male Voice Choir (Swedish: Lunds Studentsångförening, LSS, also Lunds studentsångare) is a Swedish amateur choir, which counts its history from 1831. Today one of Sweden's top male choirs, the choir has assumed many different shapes during its history. Traditionally, most members have been students of Lund University although there is no requirement of studying at the university to be able to join the choir.

The choir is known for its three larger annual concert productions, one during autumn, one during Christmas season and one during spring. Smaller local concerts are held occasionally, while regionally, the choir frequently cooperates with symphonic orchestras, such as those of nearby Malmö or Helsingborg. Nationally, the choir is most known for its annual appearance at the stairs of the Lund University Main Building every 1 May, which is broadcast on national TV, with viewer numbers ranging from approximately 300,000 to 1,000,000.
