The journalist will also be hosting a brand new daily TV show which will air across the world – including in the UK, the US and Australia.
Piers will also present a series of true crime documentaries, after previously interviewing serial killers in his show Confessions of a Serial Killer.
The TV star revealed that his new show will be a "fearless forum for lively debate" which will "celebrate the right of everyone to have an opinion."
It comes after the ex-GMB anchor left his breakfast show earlier this year, following a bitter row over his Meghan Markle comments which led to an on-air spat with his co-star Alex Beresford.
Announcing the exciting news on Thursday, Piers declared that he's "coming home", with The Sun's Editor-in-Chief Victoria Newton hailing it as a "bigger comeback than Ronaldo".
Piers also promised his future viewers: "We're going to have some fun."
Dishing the gossip on his sparkling new jobs, Piers said: "I’m thrilled to be returning to News Corp, which is where I began my media career more than 30 years ago.
"Rupert Murdoch has been a constant and fearless champion of free speech and we are going to be building something new and very exciting together.
"I want my global show to be a fearless forum for lively debate and agenda-setting interviews, and a place that celebrates the right of everyone to have an opinion, and for those opinions to be vigorously examined and challenged.

"I’m also delighted to become a columnist for The Sun and the New York Post, two brilliantly successful and popular newspaper brands.
"I’m going home and we’re going to have some fun."
Piers Morgan's new show will air on talkTV in the UK, FOX Nation in the States, and on Sky News Australia.
Media mogul Rupert Murdoch, the Executive Chariman of News Corp, said: "Piers is the broadcaster every channel wants but is too afraid to hire.
"Piers is a brilliant presenter, a talented journalist and says what people are thinking and feeling.
"He has many passionate fans around the world and we look forward to expanding his audience in the UK, at Fox Nation, Sky News Australia, The Sun and the New York Post."

Robert Thomson, News Corp's Chief Executive, said: "Piers believes passionately in the contest of ideas and the principle of freedom of speech, and he delivers his perspective with a pithy puckishness that is compelling for a broad and growing audience.
"He carbonates debate with wit, whimsy and wisdom."
It also comes as Piers is set to release a new book which will be published by HarperCollins – after the success of his previous best-selling work, Wake Up.
Charlie Redmayne, the CEO of HarperCollinsUK, added: "There is simply no one better than Piers Morgan at getting people talking and thinking about the key issues affecting society today.
"We are excited to be working with Piers on his eagerly awaited follow up book."
