Gabriel Nassif (born 8 November 1983)[6] is a French professional card player.

Gabriel Nassif first caught public attention at Magic Block Constructed Grand Prix London, 2001 where he reached the finals with his aggressive White/Blue/Red deck, and lost to German "Juggernaut" Kai Budde.

[16] With three Pro Tour Top Eights in the 2003–04 season including two runner-up finishes, Nassif earned the 2004 Player of the Year award.

He showed his gaming prowess again when he made the Top 8 of the 2006 World Championships piloting a blue/white MartyrTron deck that, according to Randy Buehler, "broke the format".

[17] Ironically, Nassif made Top 8 of the 2007 World Championships with a mono-red Dragonstorm deck designed by him and American teammate Patrick Chapin, where he again made a semifinal exit while playing against Patrick Chapin in the mono-red Dragonstorm mirror.
