The 27-year-old defender played in all-but one of Wigans Premiership matches last season and his performances at right-back earned a place in the prestigious Premiership Team of the Year as voted by the PFA.
Sporting director Damien Comolli said: "Pascal is a terrific right-back, solid defensively and good in the air. He is a complete player who can create chances offensively as well.
"Im delighted that he has joined us, he is a player who really wants to be at this club and do well for us."
Pascal won his first French cap in a friendly against Denmark in May and that was followed with a call-up to the French squad for this summers World Cup in Germany.
A smiling Pascal said: "I always wanted to be here. For me it is a footballing decision. Tottenham is a great club where I hope I can play my best football.
"Id like to thank Damien and Martin for their persistence in making this happen."
Pascal kicked-off his career at Le Havre in 1999 before switching to Bastia in 2003. He moved to Wigan in July, 2005.
The Club is delighted to announce that it has reached agreement with Wigan for the transfer of Pascal Chimbonda.
