Ben Flynn (born 23 August 1970), known professionally as Eine, is an English graffiti writer and vandal based in London.

Eine is most notable for his alphabet lettering on shop shutters in London's Brick Lane. But his distinctive style has seen him take his lettering to the streets of numerous cities around the globe from Paris to Stockholm.

Prior to becoming involved in commercial graffiti, Eine was a very famous and highly credible writer in the underground London graffiti scene. His unusual 'throw up' was created to stand out from the usual tags and dubs seen on the streets and can still be found in some dingy areas of East London.
