Following his speech the Labour leader will be interviewed by award-winning actor and writer Maxine Peake and face audience questions.
Mr Corbyn said: “I am hugely looking forward to giving this year’s Alternative MacTaggart lecture. A strong, diverse and independent media is a cornerstone of a healthy democracy and society.
“I hope to offer some perspectives on the UK media and its role today, discuss how good journalism challenges the powerful and what is holding it back in the digital age of tech giants and unaccountable billionaires.”
The politician follows in the footsteps of Russell Brand who discussed his comedy career and disillusionment with Hollywood when he gave the talk last year.
TV hosts Ant and Dec, Black Mirror creator Charlie Brooker and Scottish First Minister Nicola Sturgeon have all previously delivered the Alternative MacTaggart lecture.
The main MacTaggart lecture is the keynote speech of the festival and addresses the future of the TV industry.
