Johann Gaudenz Gubert Graf (and Freiherr) von Salis-Seewis (26 December 1762 – 29 January 1834) was a Swiss poet, writer, politician and librettist.

In the next year Salis-Seewis undertook a journey to the Netherlands and Germany (including Weimar), meeting Goethe, Herder, Schiller, Wieland, and Matthisson.

The poet colleagues of the Sturm und Drang and Empfindsamkeit dubbed him the "Bündner Nachtigall" (Graubünden nightingale).

Done with the revolutionary thoughts of the French revolution, he was a progressive representative of human rights and separated from the conservative, oligarchic tradition of his family, which controlled the Three Leagues unquestioned over decades.

Franz Schubert has set many poems of Salis-Seewis to music, like Abschied von der Harfe, Das Grab or Zum Rundtanz.
