Abdeslam Ouaddou (Arabic: عبدالسلام وادو; born 1 November 1978) is a Moroccan former professional footballer who played as a centre-back or defensive midfielder.

In the summer of 2001, Ouaddou was signed by newly promoted Premier League club Fulham for £2 million, on a four-year contract.

On 7 December 2006, he asked Olympiacos to release him free because he felt homesick and had some family problems.

He had a deal until 2012 but left after the club decided to sack him for gross misconduct, while the player wanted to cancel his contract.

This move ignited tensions amid the ongoing Western Sahara conflict between Morocco and the Polisario Front, leading to social media attacks branding him a "traitor" and racist insults.
