The former England under-21 international previously spent the 2013-14 season on loan at the Rams and now joins on a permanent basis
Derby County have completed the signing of Andre Wisdom from Liverpool in a deal reportedly worth £4.5million, with the defender penning a four-year contract.
The Championship side confirmed last month they had struck a deal with the Reds and agreed personal terms with the player.
And Derby sealed a deal for Wisdom on Monday after he successfully completed a medical, the 24-year-old following Curtis Davies to become the club’s second signing of the close-season.
Wisdom made 38 appearances on loan with Derby in 2013-14 and also had temporary spells with West Brom and Norwich City before spending last season with Red Bull Salzburg.
“I knew I was going to leave Liverpool and it was just a case of when and where to,” Wisdom told Derby’s website.
“Even though I had time remaining on my contract it was about finding the right fit.
“Everyone knows that I love Derby so I think this is a great time to make this move.”

He added: “To be honest, Derby does feel like home. When I was here before we had a great season and we were unlucky at the end not to go up, but aside from the play-off final everything clicked and we all enjoyed it.
“I feel that I played the best season of my professional career here before. Even after I left Derby and went elsewhere, I don’t think I was playing the kind of football that I was during that loan spell.
“It’s good to be back and I hope I can replicate what I did before this time around.”
Wisdom made 14 Premier League appearances for Liverpool between 2012 and 2013, before his loan stints began.
