Gary Daniel Liddle (born 15 June 1986) is an English former professional footballer who is currently manager of Northern Premier League side Whitby Town.

Liddle won several individual awards in his first season with the Magpies and would stay with Notts County for two years before subsequently signing for Bradford City, Chesterfield, Carlisle United and Walsall.

He then signed permanently for the club where he would play an integral role in central defence as Hartlepool won the 2021 National League play-off final.

[7] In August 2006, Liddle joined nearby League Two club Hartlepool United on a free transfer, signed by Danny Wilson.

In 2010, Liddle was booked in a game at Leyton Orient, which meant an instant suspension was triggered after collecting his 10th yellow card of the season.

[13] On 13 August 2011, while playing in a home league match against Walsall, Liddle suffered an injury, as his zygomatic bone became fractured in two places.

[citation needed] Liddle signed for League One club Notts County on 21 June 2012 on a two-year contract.

Liddle stated that it was Keith Curle's desire to manage in the Championship that played a big part in the switch.

"[16] He made his competitive debut for the club in a 2–1 victory over Crewe Alexandra, partnering Dean Leacock in the centre of defence.

It meant he had played every minute of the 2012–13 season, equalling a record last set by County's Pedro Richards 30 years ago.

[20] Liddle signed for Bradford City on 9 June 2014 on a one-year contract with the option of an additional year.

[21] In January 2015, he played for Bradford in their 4–2 away win at Premier League leaders Chelsea in the FA Cup fourth round.

[26] Liddle signed for League Two club Carlisle United on 13 January 2017 on a one-and-a-half-year contract for an undisclosed fee.

[30] Liddle re-signed for Hartlepool permanently for a second time after a successful loan spell in the previous season from Walsall.

[43] Following his departure from South Shields, Liddle signed for fellow National League North side Spennymoor Town in March 2023 on a deal until the end of the season.

Lee said of the signing "I worked with Gary at Hartlepool United and he's an outstanding competitor, a leader on and off the pitch and someone who can come in and help us during the final month.
