On 4 June 2011, Krul made the starting eleven for the Netherlands in a friendly against Brazil, his first cap at senior level. He went on to keep a clean sheet, pulling off a string of decent saves in a 0–0 draw. He played his second match for the international team four days later against Uruguay in a 3–4 penalty shoot-out loss, the match having finished 1–1 after 90 minutes. He was called up to the Netherlands UEFA Euro 2012 squad but did not make any appearances. In new coach Louis van Gaal's first competitive game in charge against Turkey in Amsterdam, Krul was selected as starting goalkeeper, keeping a clean sheet in a 2–0 win for the "Oranje".
