Yedlin will remain with the Sounders before joining up with his new team-mates in time for the 2015-16 Premier League campaign.
A statement on Tottenham's website read: "We are delighted to announce that we have reached agreement with Seattle Sounders for the transfer of United States international right-back DeAndre Yedlin.
"DeAndre has signed a four-year contract and will remain with Sounders before joining us ahead of the 2015-16 season."
