Switzerland was represented at the Eurovision Song Contest 1983 with the song "Io così non ci sto", composed by Thomas Gonzenbach and Remo Kessler, with lyrics by Nella Martinetti, and performed by Mariella Farré.

Swiss German and Romansh broadcaster Schweizer Fernsehen der deutschen und rätoromanischen Schweiz (SF DRS) was in charge of staging and broadcasting the selection for the Swiss entry for the Eurovision Song Contest 1983.

DRS and TSI announced their votes in a different order than usual due to technical difficulties.

The national final was broadcast on TV DRS and TSR (with commentary by Serge Moisson [fr]).

Commentary on French and Italian were provided by Georges Hardy [fr] and Giovanni Bertini respectively, through a second audio programme on TV DRS.
