The England full-back, who made his worldwide debut in the friendly defeat to France in June, will remain with Spurs until the summer of 2022.
The 26-year-old joined Spurs from Burnley for £3.5m in 2015 and has played 41 times at right-back over two seasons.
"We are delighted to announce that Kieran Trippier has signed a new contract with the club, which will run until 2022", the club confirmed in a statement. "If I get picked by the manager I will always give 100 per cent, my teammates know that, and I'll always do my best for the team and the club".
The Toffees are said to want as much as £50 million for the playmaker but with him only having a year left on his deal at Goodison Park the North London club are unwilling to pay such a fee - despite receiving a cash windfall last week when they sold Kyle Walker to Manchester City.
"Playing with the players I have here, I have progressed a lot".
But he became a regular starter earlier this year following a rumoured fall-out between Walker and the manager. At the back end of last season, I was really enjoying it.
Trippier recorded the joint-highest number of assists for a defender in the league, level with team-mate Walker, with five.
Trippier, who had interest from Everton this year, impressed for Spurs to such an extent last campaign, that he earned a call-up into Gareth Southgate's England starting line-up.
"When I first came the manager demands a lot in training and on the field". He's helped me a lot with my defensive and attacking work. If I get the opportunity to play even more, I will grab it with both hands and I won't look back.
