Shaun Johnston is a Canadian movie and theater actor best known for his role as Jack Bartlett on the CBC drama Heartland, which debuted in October 2007. He co-founded the Shadow Theatre in Edmonton and made his first professional forays in Alberta's thriving theatre scene.

Johnston is well-known for playing the role of Jack Bartlett (also known as "Grandpa Jack") on Heartland, a CBC drama that debuted in October 2007. By 2019, he had played a role on the show for 13 seasons. In 2019, and again in 2020, Johnston was nominated for a Rosie award for "Best Alberta Actor," for his role in Heartland. In 2016, Johnston described his experience on the cast of Heartland, saying "it's the best job I’ve ever had, it's the best job I'm ever going to have."

In 2020, Global News reported that Johnston was in the process of "recording and releasing" The Book of Shaun: A Story Behind His Heartland Music. The Book of Shaun is a multi-episode music project that tells "the story behind songs that he has written for the Canadian TV show" that was created in order to raise funds for a 20-home building project led by the Okanagan affiliate of Habitat for Humanity.
