Robert Glennister is a British actor who has provided English-language voices for characters in several anime titles. He was born on March 11, 1960, in Watford, Hertfordshire, England. While he is primarily known for his extensive work in live-action British television and film, his voice has also appeared in anime productions distributed in the United Kingdom.

His known anime voice acting credits are from the late 1980s and early 1990s, specifically for dubs produced by Manga Video and Manga UK. These roles include Gardeep in the Manga Video version of The Heroic Legend of Arslan, a role which is also credited on some sources. He also voiced the character Gilburgh in the OVA Dangaioh. In the series Megazone 23 Part III, he provided the voice for the character Bishop Won Dai in the Manga UK English dub. This character is a key figure in the OVA's narrative, depicted as an artificial intelligence that controls the city of Eden.

Beyond these specific credits, publicly available and verifiable information about his broader career as an anime voice actor, including recurring collaborations or notable achievements within the anime industry, is sparse. His professional profile is predominantly defined by his live-action roles on stage and screen.
