Cheng Zhi is a character from the 24 TV series. He was a minor character in Day 4 and 5 of the series, and served as one of the main antagonists of Day 6, as well as later being revealed to be the true main villain of the miniseries Live Another Day.

He first appeared in Day 4 of the series, where he was Head of Security at the Chinese consulate in Los Angeles.

At the end of Day 5, he had captured Jack Bauer and tortured him. When Jack Bauer asked Cheng to kill him, he decided not to, as he would be too valuable.

He appears as one of the main antagonists of Day 6, along with Jack's father, Philip. As Jack went off to an investigation to recover five nuclear warheads, Cheng saw this as an opportunity to increase China's power and eventually start a war between America and Russia. By the end of the day, Cheng Zhi was arrested and imprisoned by the Chinese.

In Live Another Day, Cheng Zhi is revealed to have escaped from Chinese imprisonment and he reveals himself as the true main antagonist of the season, when he kills Adrian Cross as well as his men, orders the USS Massachusetts to sink a Chinese aircraft carrier called the Shenyang, and kidnaps Chloe, who eventually escapes. He had hired Cross to build the override device, which was used by Margot Al-Harazi during the events of the season. He had also conspired with Anatol Stolnavich. Near the end of the season, Jack and Belcheck sneak through Cheng's ship and takes out several of Cheng's men. Cheng, however, has a sniper pinned down on Audrey Boudreau, and although Kate Morgan succeeded in killing the sniper, a second shooter guns down Audrey, who dies in Kate's arms. When Jack hears about this, he breaks down and nearly commits suicide. However, this caused Jack being enraged, who ruthlessly kills the remainder of Cheng's men in a shootout before finding and engaging Cheng in a final battle. The two fight briefly and brutally until Jack gains the advantage by breaking Cheng's arm and beating him senseless while angrily tells him that he should have stayed hidden like a rat and he could have died an old man before using Cheng's face and voice to confirm to the Chinese that Cheng is alive. Then, a furious Jack declares that this is for Audrey before decapitating Cheng with a katana to avenge her death.
