Kyle Broflovski is a nine-year-old Jewish kid, voiced by Matt Stone, and is one of the four main characters in South Park. Matt Stone has said that Kyle was loosely based on himself when he was younger.

He wears a bright green ear-flapped cap (or ushanka), a bright orange jacket with black-edged pockets with a dark green collar, dark green pants and lime-green mittens. He is rarely shown without his cap, but underneath it, he sports a curly red "Jew-fro", a hairstyle which he seems to resent.

He and Stan Marsh alternate as leader of their group/voice of reason. Kyle is quite witty. Unlike his best friend Stan, however, he tends to be quite cautious and is less likely to want to get involved in uncertain situations. He sometimes exhibits better moral standards than the others. Kyle is a constant target of his friend Eric Cartman's anti-Semitic abuse and is frequently singled-out and taunted by Cartman. However, Kyle seems to be unafraid of physical confrontation and has attacked Cartman several times.
