Now 14 months into his job, Tillerson has been fired through a tweet by US President Donald Trump.
Trump tweeted: "Mike Pompeo, Director of the CIA, will become our new Secretary of State. He will do a fantastic job! Thank you to Rex Tillerson for his service!"
He went on to say "Gina Haspel will become the new Director of the CIA, and the first woman so chosen. Congratulations to all."
His tweet amassed hundreds of thousands of likes and retweets.
