Wu Ban was a son of Wu Kuang (吳匡), an official who served under the general He Jin during the reign of Emperor Ling (r. 168–189) in the Eastern Han dynasty. Like his older relative Wu Yi, he served as a military general in the state of Shu Han during the Three Kingdoms period and held appointments/positions which were second to those held by Wu Yi. He was known for being bold and chivalrous. During the short reign of Liu Bei (r. 221–223), the founder and first emperor of Shu, Wu Ban served as a lingjun (領軍; a military commander).
Wu Ban participated in the Battle of Xiaoting of 221–222 against Shu's ally-turned-rival state, Eastern Wu. In the initial stages of the battle, the units led by Wu Ban and Feng Xi attacked and captured Wu positions at the Wu Gorge, which were guarded by the Wu officers Li Yi (李異) and Liu E (劉阿). As the Shu army advanced further, Liu Bei ordered Wu Ban and Chen Shi to lead the Shu navy to station at Yiling (夷陵; southeast of present-day Yichang, Hubei) in between the east and west banks of the Yangtze. After the Shu army passed through the Wu Gorge, Liu Bei instructed Wu Ban to lead a few thousand soldiers out of the mountainous terrain and set up camps on flat ground to provoke the Wu forces to attack them, but failed to lure the enemy out into a trap. The Shu forces ultimately lost the Battle of Xiaoting and retreated back to Shu.
Sometime before 231, Wu Ban held the appointment General of the Rear (後將軍) and was enfeoffed as the Marquis of Anle Village (安樂亭侯). Later in 237, he succeeded his cousin Wu Yi as General of Agile Cavalry (驃騎將軍), granted imperial authority, and elevated from a village marquis to a county marquis under the title "Marquis of Mianzhu" (綿竹侯). Wu Ban's maintained the appointment until at least 239, he is thought to have died by 243 where Deng Zhi is promoted to General of Agile Cavalry. Yang Xi's Ji Han Fuchen Zan written in 241 would have surely featured Ban so it further suggests his death is after. 
In Romance of the Three KingdomsEdit
In the 14th-century historical novel Romance of the Three Kingdoms, which romanticises the events before and during the Three Kingdoms period, Wu Ban is killed in battle during one of Zhuge Liang's military campaigns against Shu's rival state Wei. He is hit by arrows fired by archers under the command of the Wei officers Zhang Hu (張虎; Zhang Liao's son) and Yue Lin (樂綝; Yue Jin's son), falls into a river and dies.

- Histoircally, Wu Ban is listed as General of Chariots and Cavalry as late as 239, He likely died around that time of natural causes. (卻說孔明令魏延、馬岱引兵渡渭水攻北原；令吳班，吳懿引木筏兵去燒浮橋；令王平、張嶷為前隊，姜維、馬忠為中隊，廖化、張翼為後隊，分兵三路，去攻渭水旱營。是日午時，人馬離大寨，盡渡渭水，列成陣勢，緩緩而行。卻說魏延、馬岱將近北原，天色已昏。孫禮哨見，便棄營而走。魏延知有準備，急退軍時，四下喊聲大震；左有司馬懿，右有郭淮，兩路兵殺來。魏延、馬岱奮力殺出，蜀兵多半落於水中，餘眾奔逃無路。幸得吳懿兵殺來，救了敗兵過岸拒住。吳班分一半兵撐筏順水來燒浮橋，卻被張虎、樂綝在岸上亂箭射住。吳班中箭落水而死。餘軍跳水逃命。木筏盡被魏兵奪去。) Sanguo Yanyi ch. 102.
