Sweden was represented at the Eurovision Song Contest 1973 with the song "You're Summer", composed by Monica Dominique and Carl-Axel Dominique, with lyrics by Lars Forssell, and performed by Nova and the Dolls.

The Swedish participating broadcaster, Sveriges Radio (SR), selected its entry through Melodifestivalen 1973.

The winner of Melodifestivalen was the song "Sommaren som aldrig säger nej" ("Summer that never says no") performed by the group Malta.

The third place act, Agnetha, Anni-Frid, Björn, and Benny, returned to take part in Melodifestivalen 1974 under their new moniker ABBA.
