Welcome to the online home of the Princeton University Tigressions! Since 1981, the Princeton University Tigressions have entertained audiences with their unique brand of bold, contemporary all-female a cappella. From arch sings on the Princeton campus to shows in Dublin, Ireland, the Tigressions have developed a reputation for performing fresh, original arrangements of current hits and classic tunes. The group tours twice a year and performs annually at Princeton Reunions. Check out our different pages to find out more!
