奥尼特·科尔曼（英语：Randolph Denard Ornette Coleman，1930年3月9日－2015年6月11日）是一位美国籍的爵士乐萨克斯风演奏家、小提琴手、小号手和作曲家。他是1960年代「自由爵士」（free jazz）运动的主要创新者之一，自由爵士这个词也是在他的专辑所发明的。科尔曼的音色很有特色：他的热切、嚎叫般的声音受到蓝调音乐的强烈影响。他的专辑《Sound Grammar》获得了2007年的普利策音乐奖。

2015年6月11日，他因为心停止，病逝于纽约市，年85岁。

Randolph Denard Ornette Coleman (March 9, 1930 – June 11, 2015) was an American jazz saxophonist, violinist, trumpeter and composer. He was one of the major innovators of the free jazz movement of the 1960s, a term he invented with the name of an album. Coleman's timbre was easily recognized: his keening, crying sound drew heavily on blues music. He was awarded a MacArthur Fellowship in 1994. His album Sound Grammar received the 2007 Pulitzer Prize for music.
