The 29-year-old England forward, who had been strongly linked with a return to the top flight over the summer, has agreed a revised contract with the club rather than a fresh extension, with his existing deal already running through to 2030.
Bowen joined West Ham United from Hull City in 2020 and has gone on to make 280 appearances for the club, scoring 85 goals. He has captained the side since 2024, following Kurt Zouma's departure, and started every Premier League match last season as West Ham slipped into the Championship, scoring nine goals along the way. He remains one of the club's most iconic modern figures after scoring the injury-time winner against Fiorentina in the 2023 UEFA Europa Conference League final in Prague, a goal that delivered West Ham's first major trophy in 43 years.
Speaking to the club's official website, Bowen explained the pull of staying to help West Ham return to the top flight.
"My main motivation is staying and bringing this club back to the Premier League where we belong," he said.
"It was only right for me to speak at the right time. Ultimately it hurt everyone and it should hurt everyone."
Bowen also revealed he had travelled to Prague to speak directly with club directors about their plans for the season ahead.
"I flew out to Prague to meet Daniel [Kretinsky] and Jiri [Svarc] and the ambition that I got from them, certainly in terms of the direction the club wants to move in, it interests me a lot. It didn't take a lot, because this club means a lot to me," he said.
Reflecting on his six and a half years at the London Stadium, Bowen described how his relationship with the club has deepened over time.
"For me, when you're here for a longer amount of time, you gain more affection, you grow into the club more, you grow into your role more and more, and I think that's what I've done. I've been here six and a half years and transitioned from a boy to a man and I've never tried to hide away from anything," he said, before adding: "I always try and stand up for them and just kind of live my life as captain of West Ham and also as a fan as well."
Bowen missed out on a place in Thomas Tuchel's England squad for this summer's World Cup despite his 22 caps, but his decision to stay represents a major boost for West Ham as they prepare for life outside the top flight for the first time since 2011-12.
