Robin Douglas Leach (born 29 August 1941; London, England) is an English celebrity writer famous for hosting his first show, Lifestyles of the Rich and Famous, in the mid-1980s and into the mid-1990s, which focused on profiling well-known celebrities and their lavish homes, cars and other materialistic endeavors. His voice is often parodied by other actors with his signature phrase, "champagne wishes and caviar dreams". During the final season, he was assisted by Shari Belafonte, and the show was renamed, Lifestyles with Robin Leach and Shari Belafonte.

Leach voiced himself in "Peter, Peter, Caviar Eater", giving a presentation on Cherrywood Manor much like he was known to describe details on Lifestyles.
