João Gabriel Schlittler (born 10 February 1985 in Rio de Janeiro) is a Brazilian judoka, who played for the heavyweight category.

[1] In 2007, he won a silver medal for his designated category at the Pan American Games, and bronze at the World Championships, coincidentally in his home city.

He reached only into the quarterfinal round, where he lost by an automatic ippon to Cuba's Óscar Brayson, who also defeated him in the gold medal match at the Pan American Games.

[4] Because his opponent advanced further into the final match, Schlittler offered another shot for the bronze medal by defeating Lebanon's Rudy Hachache, with a tate shiho gatame (seven mat holds) and an ippon, in the repechage bout.

[5] Unfortunately, he finished only in seventh place, after losing out the final repechage bout to six-foot and eight-inch tall French judoka Teddy Riner, who successfully scored an ippon in more than a minute.
