Wenceslao Moreno Centeno, known professionally as Señor Wences, was a Spanish ventriloquist and comedian. His popularity grew with his frequent television appearances on CBS's The Ed Sullivan Show during the 1950s and 1960s. Later, he became popular with another generation of fans on The Muppet Show.

Ventriloquism is an act of stagecraft in which a person speaks in such a way that it looks like their voice is coming from a different location, usually through a puppet known as a "dummy". The act of ventriloquism is ventriloquizing, and the ability to do so is commonly called in English the ability to "throw" one's voice.
