The 22-year-old has signed a new two-year contract extension with the Owls.
“This was something I always wanted to do and I’m really pleased to be staying for another two years,” Beevers told the club’s official website.
“Sheffield Wednesday is my club and I will be here as long as they want me.
“I’ve been through the highs and lows with Wednesday and winning promotion last season was the biggest high of all.
“We are all aiming now to do well in the Championship and we’re excited about the challenge ahead.”
