Connor McGrath, a "Deadpool" fan from Canada, died in April after battling cancer.
The 39-year-old star took to Instagram to share a picture of himself along with Connor and also sent his best wishes to the boy's parents.
"My friend Connor McGrath would have been 14 years old tomorrow. He isn't here now, but he stuck around long enough to make everyone he knew fall over laughing.
"Right up to the very end he was as quick with a joke as he was with a hug. @makeawishamerica brought us together and nothing- not even a cowardly thing called cancer can take that away," he wrote.
While McGrath was undergoing the cancer treatment at a hospital in January, Reynolds hailed all the way from Vancouver to personally watched "Deadpool" with him.
