Princess Rongchang (1582-1647) was a Chinese princess, the eldest child of the Ming Dynasty Wanli Emperor and his primary wife's, Empress Xiaoduanxian, only child.

In 1596, Zhu Xuanying was given the title of Princess Rongchang. In May of the same year, she married Yang Chunyuan, for which Yang was granted a command by the Wanli Emperor. Their first son Guangkui was born in 1600.

Yang Chunyuan's mother died in January 1606, after which Yang demonstrated filial piety by grieving and refusing to eat. He died after seven days of this, leaving Princess Rongchang a widow with five sons.

Princess Rongchang's family remained closely connected to the imperial house, as shown by the appointment in 1608 of her eldest son to the Jinyiwei. In addition, the Ming Shilu note that she attended court to participate in ceremonies and rituals alongside her siblings, Princess Shouning, the King of Gui, and the King of Rui, right up until 1620.

In May 1621, Princess Rongchang's nephew, the Tianqi Emperor, conferred honours upon his paternal aunts and uncles. Princess Rongchang was given the title Grand Princess Rongchang (Chinese: 大長公主榮昌; pinyin: Dàzhǎng gōngzhǔ róngchāng).

In 1604, Princess Rongchang quarrelled with her husband. The Wanli Emperor was angered on his daughter's behalf and issued an imperial edict, scolding his son-in-law. In response, Yang abandoned his command and travelled in a small, two-person litter back to the town of his parents in modern-day Gu'an County. Incensed, the Wanli Emperor expelled Yang's father from office and sent members of the Jinyiwei to bring Yang back to Beijing, with the intention of compelling Yang to fulfil his duty as husband to Princess Rongchang. Before he was caught, however, Yang returned voluntarily to the capital and professed repentance. As punishment, Yang was sent to the Guozijian to be lectured on propriety for 100 days. Only after he had studied diligently was his father's official position to be restored.
