The Kangxi Dictionary (Chinese: 康熙字典; pinyin: Kāngxī Zìdiǎn; Wade-Giles: K'ang-hsi tzu-tien) was the standard Chinese dictionary during the 18th and 19th centuries. The Kangxi Emperor of the Manchu Qing Dynasty ordered its compilation in 1710 and it was published in 1716. The dictionary is named after the Emperor's era name.
The Kangxi Dictionary editors, including Zhang Yushu (張玉書) and Chen Tingjing (陳廷敬), partly based it on two Ming Dynasty dictionaries: the 1615 Zihui (字彙 "Character Collection") by Mei Yingzuo (梅膺祚), and the 1627 Zhengzitong (正字通 "Correct Character Mastery") by Zhang Zilie (張自烈). Since the imperial edict required that the Kangxi Dictionary be compiled within five years, a number of errors were inevitable. The Daoguang Emperor established a review board and their 1831 Zidian kaozheng (字典考證 "Character Dictionary Textual Research") corrected 2,588 mistakes, mostly in quotations and citations.

The supplemented dictionary contains 47,035 character entries, plus 1,995 graphic variants, giving a total of 49,030 different characters. They are grouped under the 214 radicals and arranged by the number of additional strokes in the character.
