Paul McLean Caddis (born 19 April 1988) is a Scottish football coach and former professional footballer who will become manager of National League North side Hereford on 1 May 2023. Caddis played in more than 350 professional matches at club level and represented his country at youth and senior levels. Having predominantly played as either a right back or right winger, he could also play as a left back or anywhere across the midfield, due to his versatility and his ambidexterity. He has played for both Celtic and Swindon Town in all positions, apart from striker and goalkeeper.

Caddis started his career with Scottish Premier League club Celtic. He broke into the first team during the 2007–08 season, but never managed to hold down a starting place over the next few years. He spent the second half of the 2008–09 season on loan to Dundee United. Caddis was sold to English League One club Swindon Town in August 2010. He spent the 2012–13 season on loan to Birmingham City, joined the club on a permanent contract in September 2013, and in the final match of that season, he scored the stoppage-time goal that saved the team from relegation from the Championship. After three-and-a-half seasons in his second spell with Birmingham, his contract was cancelled by mutual consent in January 2017. A short spell with Bury of League One preceded a season with Blackburn Rovers and seven months with Bradford City. He rejoined Swindon Town in November 2019, played his last match in 2021, and announced his retirement a year later.

Caddis played regularly for the Scotland under-21 team and also captained the side. He made his full international debut for Scotland in 2016.

He joined Fleetwood Town as an academy coach in 2021.

On 20 April 2023, he was appointed as manager of National League North club Hereford F.C. in his first managerial role.
