The Thor star celebrated the big day with an adorable throwback pic of himself and older brother Luke when they were little, hanging out near a creek with their dad, Craig.
"Happy Father's Day dad! Thanks for taking me surfing every weekend and driving me to football training and athletics training and to friends houses and anywhere and everywhere and for loving mum and us kids so much," Hemsworth captioned the endearing flashback photo. "Love u #fathersday #legend."
It's pretty clear that Hemsworth's own family loves and adores him just as much. The 33-year-old superstar's wife, actress Elsa Pataky, took to Instagram as well to heap praise on her handsome hubby.
The 40-year-old Furious 7 actress shared a gleeful snapshot of Hemsworth and their twin 2-year-old sons, Tristan and Sasha, horsing around on a playground.
"Everyday is fathers day, specially when we have a dad like ours!!" Pataky captioned the cute pic. The couple also share a 4-year-old daughter, India Rose. "Hope all the Australian dads had a great day! Happy Father's Day."
