England head coach Eddie Jones has signed a new contract to remain in the position until August 2021, the Rugby Football Union (RFU) has confirmed.
Jones' existing deal had been due to expire following the 2019 Rugby World Cup.
"Coaching England is a dream job for me, and I was delighted to be asked to stay on after Rugby World Cup 2019," said Jones.
The Australian succeeded Stuart Lancaster following England's humiliating early exit from the 2015 World Cup and has enjoyed tremendous success, overseeing victories in 22 out of 23 Tests.
Under Jones, England have won back-to-back Six Nations - completing a Grand Slam triumph in 2016 - and memorably thrashed Australia 3-0 away from home.
"I have been completely focused on developing a team capable of being the number-one rugby team in the world and winning the World Cup in 2019," Jones added.
"I never take my role as England head coach for granted and did not presume I would be asked to stay on, but, once the conversations started very recently, it was not a difficult decision to make.
"These are exciting times for English rugby, with a focused and committed squad who are full of potential and determined to win. I will continue to work as hard as I can to make England the world’s best rugby team."
Jones' new deal does contain a performance-related break clause that can be triggered following the 2019 RWC in Japan.
He is also set to play a part in identifying his successor.
"Eddie's results as England head coach speak for themselves," said RFU CEO Steve Brown.
"Under Eddie's leadership, we have risen from eighth to second in the world – and Eddie won’t be satisfied until we are number one.
"He has a 95 per cent win rate at the helm, and has been a galvanising force for the RFU, bringing focus, clarity and extraordinary commitment to the role.
"We now have a robust succession planning process in place which will avoid the historically disruptive pattern of resetting the coaching team and performance system every four years. Eddie will be a big part of this process, and wants to ensure a smooth handover to his successor."
Jones is set to name his squad for the 2018 Six Nations on Thursday.
