The 24-year-old, who joined the Premier League club in July 2008, has signed a contract to stay at White Hart Lane until 2016.
"Tottenham Hotspur gave me my chance in the Premier League and I want to go on to achieve great success here with them," Modric said on the club's website on Sunday.
"Yes, there have been enquiries from other big clubs, but I have no interest in going anywhere. Last season's top four finish was an indication of where we are as a club and I feel I can continue to improve and go on to achieve everything I want to at Spurs."
Modric had been linked in the media with a possible move to fellow Premier League sides Manchester United and Chelsea.
