"Pedro Navaja" () is a salsa song written and performed by Rubén Blades from the 1978 collaboration with Willie Colón, "Siembra", about a criminal of the same name. "Navaja" means "knife" or "razor blade" (hence an analogy to Blades' surname) in Spanish. Inspired by the song "Mack the Knife", it tells the story of a panderer's life and presumed death. The song is recognized throughout Hispanic America, as it retells scenes and stories common to these countries, although the story takes place in New York City. The song deals with life, death and the unexpected with dark humor.
