On 17 June 2011, De Laet joined newly promoted Premier League side Norwich City on loan until the end of the 2011–12 season. He made his debut in a 1–1 draw at Wigan Athletic, conceding the penalty for the Wigan goal. However, he redeemed himself with a number of excellent blocks to retain the scoreline. On 21 August, he scored his first goal for Norwich against former club Stoke City in a 1–1 draw. This was also De Laet's first senior goal. De Laet was sidelined with a back injury whilst at Norwich. He made his return from injury on 27 December 2011 against Tottenham Hotspur in a 2–0 loss. On 18 January 2012, he returned to United after Norwich cancelled his loan.
