England head coach, Jon Lewis, said they wanted to "give her every chance" of being available for the tournament, with the 18-year-old potentially a key player at the top of the order.
"It's always exciting to name a World Cup squad, and there's a great deal of talent in this group," Lewis said. "We saw a lot of good things in the West Indies, a lot of progress around shifting our mindset as a team, and I'm excited to see how we take that into to the challenge of a global tournament.
"We hope Alice is fit enough, she's worked incredibly hard alongside the medical staff to get to this point and we'll give her every chance, but as we saw in the Caribbean the depth of talent and skill in the squad is growing fast and winning tournaments is about everyone collectively embracing the moment and enjoying the journey.
"It's an honour for me to lead a team into a World Cup and I know that we will be giving it everything we have got, not only to show everyone who we are as a team and how we want to play, but also to keep inspiring people to play the game we all love so much."
Katherine Brunt, Player of the Match when England won the title at Lord's in 2009, will once again lead the line in her sixth T20 World Cup campaign. Freya Kemp, England's breakout star of the 2022 season, misses out after being diagnosed with a stress fracture in her lower back during last month's tour of the Caribbean.
