Kyle Naughton joined Norwich City on a season-long loan from Spurs on 21st July 2011.

The 22 year-old full-back began his career with Sheffield United, joining their academy at the age of seven.He spent the end part of the 2007/8 season on loan to now defunct Scottish side Gretna, making 13 appearances for them. Naughton made his first team debut for the Blades the following season, coming on as a second half substitute in the first round of the League Cup against Port Vale in August 2008. His league debut came on 20th September 2008 against Norwich City. He was voted into the 2008/09 PFA Championship Team of the Year.

The full-back joined Tottenham Hotspur in July 2009 along with fellow Blade Kyle Walker for a sum of £9million. He came on as a substitute in the 94 minute in the game against West Ham United, which was the third game in the 2009–10 season to mark his debut in the Premier League but has since found a regular place in the Spurs first team hard to come by.

He spent the 2010/11 season on loan at Middlesbrough and Leicester City. For the second time in three years he found himself in the PFA Championship Team of the Year and was also voted Leicester City’s Young Player of the Year.

He has been capped by Engand at Under-21 level but is also eligible to play for the Republic of Ireland.

Norwich are believed to have pinched his signature from under the nose of fellow Premier League newboys QPR.

Naughton was linked in June 2012 with a £4million switch to Aston Villa where he would link again with Paul Lambert

In the summer of 2014, he was linked with a move to Swansea. In January 2015, the Swansea link resurfaced along with interest from his former club Leicester. In the end Naughton completed a £5million m ove to Swansea on 22nd January 2015, funded by part of the Wilfried Bony transfer money. He had played ten games for Spurs in the 2014/15 season but was red-carded twice. He had made 74 appearances in total for Tottenham.

Naughton and Swansea were relegated to the Championship at the end of the 2017/18 season, having finished 18th.

On 20th May 2023 it was announced that Naughton would leave Swansea when his contract expired in June 2023. He had played more than 250 games for the Swans. In the end he signed a new contract with Swansea in the summer of 2023.

On 2nd May 2025 he announced that he would be leaving Swansea after ten years and 332 games. The Swans indicated they would have been prepared to offer Naughton a deal to remain at the club beyond this season, but the player has decided the time has come to move on. "It's a very emotional week, all the family are coming down for the game. They say time flies when you are having fun, and it has gone so quick," said Naughton. "It has been very difficult in some ways, but in other ways not so difficult because I think in football you have a way of knowing your time is up somewhere. That's how it goes."
