Huangchu ( ) was the era name of Emperor Wen of Cao Wei, Cao Pi, during the Three Kingdoms period in Chinese history. It lasted for a total of 7 years and was the first era name of Cao Wei. In May of the seventh year of Huangchu, Emperor Ming of Cao Wei, Cao Rui, ascended the throne and continued to use this era name.

The warlord Sun Quan used the Huangchu era name due to his submission to Cao Wei until the third year of Huangchu when he broke ties with Wei and began using his own era name, Huangwu. In later references to events during the Huangchu period, Sun Quan reverted to using the Jian'an era name from the late Han dynasty.
