The 27-year-old returns to her homeland of the United States after almost four years in Manchester, bringing an end to a successful spell at the Academy Stadium.
She initially linked up with City in the summer of 2018 when joining from Sky Blue FC in the NWSL, having spent the entirety of her career to that point in America.
Figuring in 90 games in all competitions and scoring 23 goals over the course of four seasons, the Canadian international also lifted four trophies during her stay, including two Women’s FA Cups (2019 and 2020) and two Continental Tyres League Cups (2019 and 2022).
Ahead of Thursday’s NWSL transfer deadline however, Olympic gold medallist Beckie made the switch to Providence Park outfit Portland Thorns with their new season set to begin late next month.
Speaking about her departure, Beckie said: “Finding the right words to say has been really hard, but in life and especially in sport, sometimes the best things come to an end.
“When I came to Manchester in 2018, I could have never imagined I’d stay for so long, but it was one of the best decisions I’ve ever made. In the last four seasons, the moments and memories I’ve experienced will be ones I hold onto forever.
“It’s not easy moving your whole life having no idea what was waiting for you on the other side, but what I found was a club that very quickly became close to my heart. A home away from home, friends that have become family and a place that’ll always be a part of me.
“To my teammates, thank you for who you have helped me become, for holding me accountable, for pushing and challenging me. For the constant laughter, teaching me about British humour, banter and not to take life or myself too seriously. I will miss you all immensely.
“To the staff, coaches and backroom, former and current, many of who have been here from the beginning, thank you for helping me grow and always making this an environment anyone would want to be in. You have been one of the best groups of people I’ve ever worked with.
“To the fans, I’ve felt your unwavering support since the beginning, your commitment and dedication to the club and our team is unmatched. You’ve stuck with us through it all and made my time here so special. The team doesn’t exist without you all - please know how appreciated you are.
“It has been an absolute honour to wear this kit. Every day I’ve stepped inside this building I have felt so much gratitude to be a Manchester City player, and I can only hope I’m leaving it in a better place than I found it.
“I came as a player and I’m leaving as a life-long fan. Once a blue, always a blue.”
Head Coach Gareth Taylor added: “On behalf of everybody at Manchester City, I’d like to thank Janine for everything she has done for the Club during her time here.
“She has been an important member of the team over the past four years and played a huge part in some of our most memorable moments, whether that be in league fixtures or cup competitions.
“We’d like to wish her all the very best for the future and again, thank her for all her contributions.”
