The Chilean international had been linked with a move to Manchester United and Bayern Munich, after a season of impressive performances for the Turin-based club.
The defending Serie 'A' champions signed the 25-year-old from Bayer Leverkusen in 2011, and he played a key role in last year's unbeaten title success.
Smooth passage to the Champions League quarter-finals, including several commanding displays at the heart of a talented three-man Juventus midfield, has led to speculation that a big-money summer bid could be forthcoming for the midfielder.
Juventus's Champions League quarter-final opponents Bayern Munich were reportedly keen, while Manchester United have been long-term admirers.
But Vidal insists he's committed to Juventus, and has no intention of leaving anytime soon.
Speaking to Tuttosport, Vidal said: "I can promise the fans that I'm staying, 100 per cent. I intend to remain here - I have a contract here for the next three and a half years."
The Santiago-born midfielder, along with Andrea Pirlo and Claudio Marchisio , forms one part of an imposing three-man midfield. And Juventus have serious ambitions of a first Champions League trophy since 2003.
The Serie 'A' league leaders face Bayern Munich, conquerers of Arsenal in the last-16, while Manchester United were knocked out by Real Madrid at the same stage.
Sir Alex Ferguson has been linked with a number of centre-midfielders in recent seasons, but he's yet to strengthen the position.
