Aisin Gioro Yongxing (永瑆; 22 March 1752 – 10 May 1823) was the Qianlong Emperor's 11th son and Qing Dynasty imperial prince.

Yongxing was born on 22 March 1752 to Imperial Noble Consort Shujia, a member of Korean Jin clan. Yongxing was considered to be one of the most talented sons of the Qianlong Emperor. He had good relationship with 12th prince Yongji and 15th prince Yongyan in his childhood.^[1] He was known for his calligraphy, that's why he was commissioned by his half-brother to create plaques and stellas in the Yu Mausoleum of Eastern Qing tombs.^[2] His first work was "Lyrics of Peaceful Summer", dedicated to Empress Xiaoshengxian. Empress Dowager expressed her fondness of that work by creating a library named Yijingzhai, after that Yongxing chose his art name.^[3] The prince later wrote cycle of poems named after his studio. Furthermore, his literary works included "Listening to the Rain" and "Series of Ancient Dragon".^[4] Yongxing was particularly famous for relationship with top artisans of Qianlong era, such as Weng Fanggang, Liu Yong and Tiebao (member of Donggo clan), which earned a name of "Four Schools of Qianlong era".^[5]

He was granted the title Prince Cheng of the First Rank in 1789. In 1792, Minister of War Qinggui used Yongyan's letter to Yongxing in the entry of his memorial. Qinggui was accused of disrespect and punished for his action. In 1799, Yongxing was appointed as a member of Council of State and subsequently tasked with overseeing Ministry of Revenue. In 1813, when Eight Trigrams attempted to storm the Forbidden City, Yongxing supported his nephew in killing the uprisers. In 1819, he was dismissed of his duties due to offensive behaviour.^[6] In 1820, when Jiaqing Emperor became severely ill in Chengde Mountain Resort, he was summoned back to Beijing. In 1822, he presented a set of 16 ritual vessels to the imperial court. Yongxing died on 10 May 1823 and was posthumously honoured as Prince Chengzhe of the First Rank (成哲亲王, meaning "virtuous and sagacious").

Yongxing was married to Fuheng's daughter, Lady Fuca.^[7] Later, he took his palace maid Duanyun as a secondary consort, following example of Yongxuan, who also took his servant as a concubine.

Princess consort spent monthly 817 taels of silver in 1795, more than Crown Princess, who spent only 290 taels of silver. In 1796, after the promotion of lady Hitara, spendings of Yongxing's consorts were lower than expenses of imperial court.^[8]
