A tenso (Old Occitan: [tenˈsu, teⁿˈsu]; French: tençon) is a style of troubadour song. It takes the form of a debate in which each voice defends a position; common topics relate to love or ethics. Usually, the tenso is written by two different poets, but several examples exist in which one of the parties is imaginary, including God (Peire de Vic), the poet's horse (Bertran Carbonel) or his cloak (Gui de Cavalhon). Closely related, and sometimes overlapping, genres include:

In Italian literature, the tenso was adapted as the tenzone. In Old French, it became the tençon.

In the Galician-Portuguese lyric, it was called tençom.
