The 22-year-old United States full-back has followed Fabio Borini, Jeremain Lens, Yann M'Vila, Ola Toivonen, Younes Kaboul, Seb Coates and Adam Matthews to the Stadium of Light as head coach Dick Advocaat attempts to avoid a repeat of the struggles which have beset the club in the last two seasons.
Yedlin, who joined Spurs from Seattle Sounders in August last year, made his Barclays Premier league debut against Aston Villa in April.
He said: "I'm delighted to be given the opportunity to play for a club with such great history
I've heard fantastic things about Sunderland and the supporters from Claudio Reyna and Jozy Altidore
Claudio speaks very highly of Dick Advocaat from his time at Rangers."
Yedlin is currently on international duty with Jurgen Klinsmann's USA side, who have friendlies against Peru and Brazil.
