Meagan's international debut came in May 1961 when he was chosen to play in the wing half position during a World Cup qualifier against Scotland at Hampden Park.
Although Ireland lost 4–1, Meagan impressed enough to be selected to play in the return game the following week at Dalymount Park.
The 1970s Ireland finished bottom of their qualification group for the 1972 European Championships, ending Meagan's tenure as manager.
