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.

The protagonist frequently breaks the fourth wall, providing exposition, internal monologues, and running commentary to the audience.

[11][12][13] The initial idea of the character of Fleabag came from a challenge by a friend, where Waller-Bridge was given the task of creating a sketch for a 10-minute section in a stand-up storytelling night.

The silent retreat that Fleabag and Claire attend on mother's day was filmed at Hedsor House in Maidenhead, Berkshire.

The second series premiered with a family dinner party filmed at the American steakhouse, Smith & Wollensky in Covent Garden.

The first series received an average rating of 8.5/10, based on 42 reviews, with the site's critical consensus reading: "Clever and viciously funny, Fleabag is a touching, wildly inventive comedy about a complicated young woman navigating the aftermath of trauma.

"[22] The second series received an average rating of 9.3/10, based on 99 reviews, with the critical consensus stating: "Fleabag jumps back into the fray with a bracing second season that upholds its predecessor's frenzied wit and delicate heart, replete with Phoebe Waller-Bridge's indefatigable charisma".

[25] Emily Nussbaum of The New Yorker described the first series as "a precision black-humour mechanism, a warped and affecting fable about one single woman's existence.

"[26] Maureen Ryan at Variety called it "scathingly funny", concluding that "long after it's pulled you in with its irreverence and jokes about sex, and beguiled you with its cutting wit and messily human characters, it reveals that it's actually a tragedy".

"[29] Mary McNamara of the Los Angeles Times commended its unpredictability, acting, and "clear eye for truth that often becomes, like all good comedy, quite devastating".

[31] Mary Elizabeth Williams of Salon praised its "brilliant swan song", finding the series's conclusion satisfying and "well-earned".

[38] Former United States President Barack Obama named the second season of Fleabag among his favourite films and television series of 2019.
