Xu Chu (pronunciationⓘ) (died c. 230),[a] courtesy name Zhongkang, was a Chinese military general who lived during the late Eastern Han dynasty and the Three Kingdoms period of China.

He was described to be a big and strong man, yet simple minded and honest, so he was nicknamed "Tiger Fool" by his men.

Xu Chu was from Qiao County (譙縣), Pei State (沛國), which is present-day Bozhou, Anhui.

[4] Towards the end of the Eastern Han dynasty, Xu Chu rallied thousands of his clan members and they constructed a fortress to fend off the Yellow Turban rebels.

Xu Chu participated in the Battle of Ye in 204 and received the title of a Secondary Marquis (關內侯) as a reward for his efforts.

[7] In 211, during the Battle of Tong Pass against a coalition of northwestern warlords led by Ma Chao and Han Sui, Cao Cao led his troops north across the Wei River in an attempt to circle to the rear of the enemy.

Xu Chu killed several enemies and was promoted to Military Guard General of the Household (武衞中郎將) for his achievement.

Cao Ren asked Xu Chu to join him in the side room for a chat.

Later, someone told Xu Chu: "The General (Cao Ren) is a close relative and important subject of the King.

Xu Chu replied: "He may be a close relative and important subject of the King, but he's in charge of external defences at the borders.

Cao Rui enfeoffed Xu Chu as the Marquis of Mou District (牟鄉侯) and granted him a marquisate comprising 700 taxable households.

In 263, when the Wei state launched a major campaign to conquer its rival state Shu, Xu Yi served as an officer under the Wei general Zhong Hui, who tasked him with overseeing the construction of a road leading into Shu.

However, when the road turned out to be poorly built, Zhong Hui disregarded Xu Yi's background and had him executed for failing his mission.

[16] Chen Shou, who wrote Xu Chu's biography in the Sanguozhi, commented that Xu Chu and Dian Wei were powerful bodyguards and were comparable to Fan Kuai, a general who served under Liu Bang, the founding emperor of the Han dynasty.

His bravery and strength are emphasised by a fictitious story in Chapter 59, when he duels with Ma Chao during the Battle of Tong Pass.

Xu Chu is featured as a guardian spirit alongside Dian Wei of General Cao Yanbing in the anime "Rakshasa Street".
