Having first won the award in 2018 whilst with Bristol City, the 21-year-old has now retained the trophy for a third successive campaign.
It is the longest period in which any player, male or female, has claimed the prize in consecutive seasons since the award’s inception in 1974, making her the PFA's most decorated award winner.
The winger grabbed 21 goals in 37 appearances for City across 2021/22, seeing her finish as the Club’s leading scorer, while her total of ten assists was also the most of Gareth Taylor’s side.
The 21-year-old fended off competition from Chelsea’s Lauren James, Arsenal’s Frida Maanum, Manchester United midfielder Ella Toone, Tottenham’s Jessica Naz and Brighton defender Maya Le Tissier to claim the prize.
Named as part of Sarina Wiegman’s provisional squad for July’s European Championships, Hemp could yet claim further silverware with the Lionesses this summer.
Reflecting on her achievement, Hemp said: "It’s an honour to get this again. I think especially for it to be voted for by players that I’ve played against and come up against.
“I look to many of them as role models as well so it’s an honour to be picked from them.
"Coming off the back of a great season, I’ve also got a lot to thank my teammates for to be honest, because I think they make me look better than I actually am!
“We’ve got a fantastic squad and players who get me the ball in good positions and strikers who can finish the crosses that I put in wherever I put them.
“I’ve got a great set of staff as well, people who are always pushing me, wanting me to get better so, I appreciate it and I know there’s so much more to come.
“I'm going to keep working hard for that to make sure that I continue on the right path.”
City Head Coach Gareth Taylor added: “We are all absolutely delighted that Lauren has gained the recognition she deserves by winning this award once again.
“A fourth PFA Young Player of the Year award – and third in succession - is an astonishing feat, and one that she fully deserves for her hard work over the past four years at the Club.
“She has firmly established herself as a key member of the group here and we are very lucky to have her.
“At 21, it is incredibly exciting to think that the best years of her career are still ahead of her and hopefully they will be spent winning plenty more trophies here at Manchester City.
“Lauren’s motivation to keep on improving and general attitude around the training ground makes me confident that she will continue to hit new heights in the coming years, supported by the brilliant team and coaching staff around her.”
