Kelvin Leerdam (Dutch pronunciation: [ˈkɛlvɪn leːrˈdɑm]; born 24 June 1990) is a Surinamese professional footballer who plays as a right-back for Heracles Almelo and Suriname national team.

Leerdam joined a successful generation in Feyenoord U17, where he had to compete with players like Leroy Fer, Georginio Wijnaldum and Kevin Wattamaleo for a place on the midfield.

In January 2007, Leerdam was invited to the first team's training camp in Belek, Turkey, by Feyenoord manager Erwin Koeman.

In the UEFA Cup away match against Deportivo la Coruña (3–0), Leerdam replaced Karim El Ahmadi in the 56th minute.

[13] Three days later, Leerdam scored on his league debut for Vitesse in their 3–1 home victory over Heracles Almelo, netting the opener in the 27th minute.

[14] Leerdam went onto score eight times in total during the 2013–14 campaign and started to attract interest from Vitesse's feeder club, Chelsea during January 2014.

[15] During the 2015–16 campaign, Leerdam was dropped by interim-manager Rob Maas for the foreseeable future after the full-back discredited Vitesse in a recent interview.

On 31 March 2017, it was announced that Leerdam would leave Vitesse along with Arshak Koryan, Wouter Dronkers and Ewout Gouw at the end of their current deals in June 2017.

[17] He played as Vitesse won the final of the KNVB Beker 2–0 against AZ Alkmaar on 30 April 2017 to lead the club, three-time runners up, to the title for the first time in its 125-year history.
