The 19-year-old moves to the League One club after recently signing a new long-term contract with the Black Cats.
Young impressed during his time at Salford City, where he made 64 appearances over two seasons and earned a nomination for the EFL League Two Young Player of the Year award.
The England youth international also gained valuable experience during a loan spell at Darlington in the National League North.
“Matty has got a really bright future ahead of him and this loan is another crucial step in his ongoing development as a top young goalkeeper,” said Sunderland’s Director of Football Florent Ghisolfi.
“The whole goalkeeping department deserves credit for his continued growth. We’re excited about watching his career continue to make forward strides at Huddersfield next season. We wish him and the club well for the 2026/27 campaign.”
