De Bruyne found there was no room for him in Chelsea's plans 18 months ago, after he signed from Genk and was swiftly loaned out to Werder Bremen for the 2012-13 campaign.
And despite Jose Mourinho affording him the chance to win him over this season, De Bruyne has been a peripheral figure around the first-team squad.
Chelsea said in a statement: "Kevin De Bruyne has today (Saturday) completed a move to Wolfsburg.
"The Belgian joins the Bundesliga club having made five starts for Chelsea, with a further four appearances as a substitute."
