Shi Jin is a fictional character in Water Margin, one of the Four Great Classical Novels in Chinese literature.

Finding Shi Jin's fighting skill wanting, Wang makes a frank comment which the young man overhears.

When told the news, the other two chiefs, Zhu Wu and Yang Chun, comes to the village to beg Shi Jin to arrest them as well so that they can fulfill their oath to die together.

One day, a servant of Shi Jin, when returning from an errand to invite the bandit chiefs to a feast at his master's house, loses the reply letter of the outlaws after getting drunk and falling asleep in a grove.

In Weizhou (渭州; around present-day Pingliang, Gansu), Shi Jin could not find his teacher but meets and befriends Lu Da, a local garrison officer.

One day he learns that Prefect He, the governor of Hua prefecture, or Huazhou, has abducted the daughter of a painter to force her to be his concubine.

But Prefect He spots Lu behaving strangely in a crowd as he contemplates assassination seeing the official appearing in public with his guards.

Posing as imperial officials sent by the Song court to pray at the hallowed Mount Hua, the Liangshan team commands Prefect He to come out of the city to meet them.

When Liangshan attack Dongping prefecture for food, Shi Jin volunteers to infiltrate the city to launch an internal sabotage.

Later, he and five other Liangshan heroes are sent to attack Yuling Pass (昱嶺關; near present-day Zhupu Village, She County, Anhui), which is guarded by Pang Wanchun.
