Steve Marlet (born 10 January 1974) is a French former professional footballer who played as a forward. He was capped 23 times and scored six goals for the France national team, winning the Confederations Cup in 2001 and 2003 and featuring at Euro 2004.

Marlet was born in Pithiviers, Loiret.

Marlet began his professional career with Red Star.

Marlet held the record for Fulham's biggest transfer fee until July 2008, as the newly promoted Premier League team paid £11.5 million to sign him in August 2001 from Lyon. His expectations was well received by France national team coach Roger Lemerre, suggesting: "He will progress at Fulham". However, he only managed eleven goals in 54 league games, as then-manager Jean Tigana was dismissed during the season. He played just one game in the 2003–04 season for Fulham, in which he scored. He was then loaned out to Marseille on 27 August, with an option to sign permanently.

While on loan, Marlet partnered Didier Drogba up front as Marseille advanced through the 2003-04 UEFA Cup, before losing the final to Valencia.

Marlet's poor performances for Fulham led to chairman Mohamed Al-Fayed taking Tigana to the Court of Arbitration for Sport for the high transfer fee. Tigana, who had ties to Lyon and had briefly been Marlet's agent, was accused of signing him for an exorbitant fee and taking a cut of the fee for himself. The charges were quickly dropped.

On 21 August 2005, after his release from Fulham, Marlet signed a one-year deal with the option for a second year, at VfL Wolfsburg of the German Bundesliga. On his arrival, manager Thomas Strunz said: "Steve Marlet is very well-known in international football, a player who is fast and versatile".

Marlet only scored one Bundesliga goal and was not given the second year of his contract. He trained for two weeks with Paris St. Germain before signing a one-year deal at Lorient, newly promoted to Ligue 1. He was attracted by the attacking style of manager Christian Gourcuff.
