Hamill will be honoured at next year's Oscar Wilde Awards, which is part of the US-Ireland Alliance to celebrate the contribution Ireland makes to film, television and music.
Mark Hamill isn't the first Star Wars actor to be honoured by the Oscar Wilde Awards - the late Carrie Fisher also received an award a few years ago.
" I find it meaningful because Ireland has always had a very special place in my heart, both personally and professionally," he said.
"I attended the Oscar Wilde Awards when my dear friend Carrie Fisher was a recipient," Hamill said of the announcement.
"Now it's my honour to be recognized by the US-Ireland Alliance in the same way."
The US-Ireland alliance said: "With Luke Skywalker to feature prominently in the Rian Johnson-directed The Last Jedi, Mark has spent a good deal of time filming in Ireland. It seems especially appropriate that we honor him in 2018."
