Scarratt will continue coaching at Premiership Women’s Rugby club Loughborough Lightning, but will also work for the Rugby Football Union in a specialist coaching and mentoring role.
“While it’s the right moment to stop playing, I’m really excited to stay involved with the RFU and to help shape the future of the game,” she added.
“The women’s game is in an amazing place, and I’m proud to still be part of its journey.”
RFU chief executive Bill Sweeney said: “Emily’s contribution to English rugby cannot be overstated – on and off the field she has been a model professional, a leader, and a role model for thousands of girls who have picked up the ball because of her.”
Having made her international debut in 2008, the last of Scarratt’s 119 caps came in the opening match of the Rugby World Cup in Sunderland, when she came off the bench. She had been expected to feature later in the tournament but picked up a shoulder injury.
She went on to support the squad throughout the tournament in a variety of off-field roles,, external earning yet more fans for her humility and dedication to the squad.
Making it to her fifth Rugby World Cup was a huge achievement for the centre, who spent 13 months on the sidelines following a serious neck injury that required surgery in 2023.
She is considered to be one of the sport’s greatest players, and delivered a stellar performance in the 2014 Rugby World Cup final, scoring 16 of England’s 21 points as they beat Canada in Paris.
Scarratt also captained the Team GB Sevens team at the Rio Olympics in 2016.
