The striker finished as the top goalscorer in the Premier League this season.
The 22-year-old finished this past campaign as the Premier League's top goalscorer with 25 strikes to his name to help Mauricio Pochettino's men confirm their place in the title picture.
And that form saw Roy Hodgson pick the forward in his provisional squad for the tournament which starts later this summer, and Henry has earmarked him as the man that will be instrumental if the Three Lions are going to go a long way in the competition.
"I have to mention Harry Kane. You finally have a guy who can bail you out in some games. If you are defending you know he can always score at any moment," he told Sky Sports.
While Kane's form at White Hart Lane cannot be questioned, he is more of an unknown quantity on the international stage with only 11 caps to his name and with no major tournament experience for the senior side under his belt.
But he proved in the friendly with Germany in March that he has the ability to make a difference against the very best sides as he scored a goal in England's 3-2 win.
And after scoring in the victory over Turkey on Sunday - though he did also miss a penalty - it appears that he is raring to go to prove that Henry was right to build him up.
