Radhi Ben Abdelmajid Jaïdi (Arabic: راضي بن عبدالمجيد جعايدي), born 30 August 1975 in Tunis) is a retired Tunisian footballer. He played as a centre back. He is currently an Under-21s coach at Southampton.
Jaïdi joined Birmingham City in the summer of 2006 for £2 million. He made his debut in a 1–0 win over Crystal Palace in the early stages of the season although he almost scored an own goal in this match. After three years with the club, he was not offered another deal when his contract expired at the end of June 2009.
In August 2009, Jaïdi passed a medical and agreed personal terms with Football League One club Southampton, but the transfer stalled when doubts arose over the player's eligibility for a work permit. However, on 2 September 2009, the club confirmed that Jaïdi had signed a two-year contract, subject to work-permit clearance. He received his international clearance on 10 September, and made his debut as a 77th-minute substitute at Charlton two days later. He scored his 1st goal for the Saints in the 1–1 draw away to Carlisle United on 26 September; the 95th-minute goal came from a free kick which earned his side the draw. His first goal in the 2010–11 season came in a 4–1 victory over Huddersfield Town.
Jaïdi was also a regular in the Tunisia line-up and was selected by coach Roger Lemerre for the 2006 World Cup. He scored the goal which secured a 2–2 draw in their opening game against Saudi Arabia. He had previously been part of Tunisia's 2004 African Nations Cup-winning squad, and played in the 2002 World Cup. He captained the Tunisian national team in the 2008 African Cup of Nations, where they went out in the quarter finals to Cameroon.
