Chi Ling Dai Cheng (July 15, 1970 – April 13, 2013) was an American bassist known for his work with American alternative rock band Deftones.

Chi’s career started while enrolled at the Sacramento campus of the University of California, joining the Deftones. He would be in the band for 5 studio albums from 1995 to 2006 and an album that has not been released by the band.

On November 4th, 2008, Chi and his sister Mae were involved in a rollover collision in Santa Clarita, California that sent Chi into a coma that he would remain in until April 2013, remaining in a semi-conscious state. On April 13th, 2013, Chi was rushed to the hospital after showing signs of cardiac arrest and was pronounced dead on arrival. He was only 42 years old at the time of death. He is survived by his son, Gabriel Cheng, who has followed in his father’s footsteps as a bassist.

A seat belt awareness organization was founded in 2013, named Buckle Up for Chi. Chi was not wearing a seat belt at the time of the 2008 collision and was ejected from the vehicle.
