The Happy Days actor has been at the town’s old Girl’s Grammar School, to film scenes for CBBC series Hank Zipzer.
Henry Winkler co-wrote the children’s book Hank Zipzer: The World’s Greatest Underachiever and stars in the TV adaptation as Mr Rock, Hank’s favourite teacher.
Adam Ellis said on Twitter: “Saw The Fonz down Dewsbury today dressed as Santa. Standard.”
Craig Lightowler said on Facebook: “Met the Fonz in town today, he was filming a scene for his new show. I asked him how he was finding Dewsbury, he said everything has been great.”
The feature-length episode will be shown over the seasonal period and follows Hank as he prepares for Christmas and a new baby brother.
Cheryl Taylor, Controller of CBBC, said: “Our fabulous standalone Christmas special will delight Hank’s growing army of fans.
“We’re thrilled to have a full 90 minutes to enjoy his Christmas capers alongside partner in crime Henry Winkler.”
