The 35-year-old, who played more than 100 games for Huddersfield and led them to promotion last season, will become part of manager David Wagner's technical staff.
"I'm very happy that Mark is becoming part of my backroom staff," Wagner told the club's website.
"From my first day in England, Mark has been one of the biggest positives. He is a huge influence in our dressing room -- a total professional with a winning mentality.
"I believe the qualities that Mark has as a person and a footballer should make him an excellent coach. I know retirement can feel like a sad day as a former player, but he has so much still to give this club and football and that is exciting."
Huddersfield begin their season on Saturday away to one of Hudson's former clubs, Crystal Palace.
