Jovelian de Koker (born 28 February 1992) is a South African rugby union player for Marmande in Fédérale 1 in France.
At the start of 2013, De Koker represented Villagers Worcester in the inaugural edition of the SARU Community Cup competition.
A much-improved performance from Boland saw them finish in second spot in the league to qualify for the semi-finals, helped by tries from De Koker in their matches against Limpopo Blue Bulls U21 in Bela-Bela[5] and Pumas U21 in Nelspruit.
[11] He made two more starts and one appearance off the bench, but once again missed out on the play-offs, by one point to eventual finalists Falcons.
De Koker began the 2015 Vodacom Cup as first-choice scrum-half for the Boland Cavaliers, starting their first three matches of the campaign.
