The 26-year-old Scotsman will star in the touring production of the Andrew Lloyd Webber musical, which begins in Bromley, south London on August 20.
He will play Joseph at the same time as the show's winner Lee Mead, who begins his West End run next week.
The casting of Chalmers is expected to spark outrage among fans, because the show's host Graham Norton always said that: "There can only be one Joseph".
