Paul Boertien (born 20 January 1979 in Haltwhistle, Northumberland, England) is an English former footballer who has played for seven English clubs.

Boertien began his career in Carlisle United in August 1996. His first league game for Carlisle United was against Walsall on 4 October 1997, while his first goal for the club from Cumbria came against Swansea City on 13 February 1999.

Boertien signed for Derby County in March 1999 for a fee of £250,000. He made his debut on 16 May 1999 against Chelsea. He then went out on loan to Crewe Alexandra in 2000 before returning to score his first goal in a 2–0 Premier League win over Derby's local rivals Leicester City on 16 April 2001. Boertien was in and out of the team over the next three years, including a loan spell at Notts County in 2004, but suffered from an unlucky run of injuries between 2004 and 2006 which saw him a virtual ever-present in the treatment room. He made his return to the first team after almost two years in a 2–1 victory over Hull City in August 2006. However, an injury sustained during the Boxing Day defeat to Wolverhampton Wanderers, coupled with the signing of Blackburn Rovers Jay McEveley, saw Boertien slip to third choice left back and manager Billy Davies announced his contract would not be renewed at the end of the season, after over eight years at Pride Park.

On 22 March 2007, Boertien joined Derbyshire club Chesterfield^[2] on a month's loan in an attempt to regain match fitness and put himself in the shop window. He then returned to Derby,^[3] but was released shortly afterwards.^[4]

In July 2007, Boertien was given a trial by Oldham Athletic, appearing in a friendly against Barrow but was not offered a contract.

After his failed trial with Oldham Athletic, Boertien joined League One Walsall on 27 July 2007.^[5] On 6 May 2009, Boertien was released from Walsall after being told that his contract would not be renewed.
