Florence Welch revealed the news on social media and said her heart was "aching" that she had to push back her Dance Fever tour to 2023.
The band had been due to perform in Birmingham on Thursday at the Utilita Arena, with fans now being asked to hang on to their tickets.
The singe posted on social media: "I'm so sorry to say that after an x-ray it seems I was dancing on a broken foot last night. It is not in my nature to postpone a show, a certainly not a UK tour, but I'm in pain and as dancers know, dancing on an injury is not a good idea. And (I) have been told not to perform to avoid further damage.
"Please hang on to your tickets. We are working our hardest to reschedule these dates for next year and we will let you know as soon as possible. I'm heartbroken as the 'Dance Fever' tour has been my favourite show we have ever put on. The communion with you. Your beautiful faces shining.
"I love you so much and I'm so sorry to anyone who is disappointed. My heart is aching. I can't wait to be back on my feet and back in your arms."
