Jordan Tannahill (b. 1988) is a Canadian novelist, playwright, and director.  

He has been described by The Toronto Star as being "widely celebrated as one of Canada’s most accomplished young playwrights, filmmakers and all-round multidisciplinary artists"; by CBC Arts as "one of Canada's most extraordinary artists"; and by The Montreal Gazette as "the hottest name in Canadian theatre." His plays have been translated into multiple languages and widely honoured in Canada and abroad. Jordan has twice won a Governor General's Literary Award, Canada's highest state honour for literature; winning the Governor Generals Award for Drama in 2018 for his plays Botticelli in the Fire & Sunday in Sodom, and in 2014 for Age of Minority: Three Solo Plays. He was also a finalist for the award in 2016 for Concord Floral. 

His plays, performance texts, and productions have been presented at venues including at The Young Vic Theatre (London), Sadler's Wells (London), The Kitchen (NYC), Festival d'Avignon (Avignon), The Lincoln Centre (NYC), Volkstheater (Vienna), Canadian Stage (Toronto), The Art Gallery of Ontario (Toronto), The National Arts Centre of Canada (Ottawa), Woolly Mammoth Theatre (Washington DC), The Edinburgh International Festival, and on London's West End.

His books include the autofiction novel Liminal (House of Anansi, 2018), and Theatre of the Unimpressed: In Search of Vital Drama (Coach House Press, 2015). As a filmmaker, Jordan's work has been presented in festivals and galleries the world over. His virtual reality performance Draw Me Close, produced by the National Theatre (UK) and the National Film Board of Canada, was presented at both the Tribeca Film Festival and Venice Biennale in 2017, and ran at London's Young Vic Theatre in January 2019. Jordan has also worked in dance, choreographing and performing with Christopher House in Marienbad for the Toronto Dance Theatre in 2016 and 2019, and writing the text for Akram Khan's celebrated dance pieces Xenos and Outwitting the Devil, both currently touring internationally.  

From 2008 - 2016, Jordan wrote and directed plays through his theatre company Suburban Beast. The company’s work was staged in theatres, art galleries, and found spaces, and often with non-traditional collaborators like night-shift workers, frat boys, preteens, and employees of Toronto's famed Honest Ed's discount emporium. From 2012 - 2016, in collaboration with William Ellis, Jordan ran the alternative art space Videofag out of their home in Toronto’s Kensington Market neighbourhood. Over the four years of its operation, Videofag became an influential hub for queer and avant-garde work in Canada. The Videofag Book was published by Book*hug Press in 2017.

He currently lives in London, UK.
