Green, who has made more than 650 appearances during his career and played for Norwich City, West Ham United and Queens Park Rangers in the Premier League, has been capped 12 times by England.
Huddersfield boss David Wagner said Green had been brought in to add experience to his promoted team, who are unbeaten in their first three Premier League games and third in the standings behind Manchester United and Liverpool.
"I think it makes total sense to bring Rob Green in because after Jonas Lossl, who has done an excellent job so far, we have very young goalkeepers with Joel Coleman and Ryan Schofield," the German told the club website.
