Zhou Tai (pronunciationⓘ) (died c. 223), courtesy name Youping, was a military general serving under the warlord Sun Quan during the late Eastern Han dynasty and early Three Kingdoms period of China.

Out of negligence, Sun Quan did not set up defence posts, so when thousands of bandits suddenly attacked Xuancheng, he attempted to flee.

Only Zhou Tai, with his spirits roused, rushed to protect Sun Quan, emboldening those near him and making them able to fight again.

When the bandits finally dispersed, Zhou Tai had sustained 12 deep wounds all over his body and he took a long time to recover.

[4] In 199, Zhou Tai followed Sun Ce to attack Liu Xun at Wan County (皖縣; present-day Qianshan County, Anhui) and Huang Zu at Jiangxia Commandery (江夏郡; commandery capital in present-day Xinzhou District, Wuhan, Hubei).

Zhou Tai participated in the defence of Ruxu, and Sun Quan's forces succeeded in driving back the invaders.

[7] The Jiang Biao Zhuan (江表傳) further described this incident as follows: Sun Quan held [Zhou Tai's] arm and tears crossed his face.

[9] In 219, Sun Quan sent his general Lü Meng to invade and seize Liu Bei's territories in Jing Province, which were defended by Guan Yu.

He also appointed Zhou Tai as General of Vehement Might (奮威將軍) and awarded him the title "Marquis of Lingyang" (陵陽侯).

Later in 228, he participated in the Battle of Shiting under Lu Xun's command, which saw a victory for Wu forces over the Wei army led by Cao Xiu.

He died in 230 and was succeeded by his younger brother, Zhou Cheng (周承), who inherited his military appointment and their father's marquis title.
