Alfred Lagarde (1948-1998) was a noted Dutch disc jockey who dubbed Telly Monster on Sesamstraat, the Dutch co-production of Sesame Street.

After a few brief appearances, Telly became a main character in the late 1980s. His Dutch name is Teevee Monster, or simply Teevee ('tay-vay').

After Lagarde died in 1998, Fred Meijer took over as Telly's voice.
