Le trésor de la langue (English: The treasure of language) is an album by guitarist René Lussier.

The album includes a poem by Richard Desjardins entitled "Qui s'en souvient?

The liner notes also refer to contemporary events in Canadian politics as a "poisoned chalice" for the survival of the language.
