Fleabag is a British comedy-drama television series created and written by Phoebe Waller-Bridge, based on her one-woman show first performed in 2013 at the Edinburgh Fringe Festival. It was originally produced by Two Brothers Pictures for digital channel BBC Three in a co-production agreement with Amazon Studios. Waller-Bridge stars as the title character, a free-spirited but angry and confused single young woman in London.
