Khouw Kim An, 5th Majoor der Chinezen (Chinese: 許金安; pinyin: Xǔ Jīn'ān; Pe̍h-ōe-jī: Khó͘ Kim-an; 1875 – February 13, 1945) was a high-ranking Chinese Indonesian bureaucrat, public figure and landlord who served as the fifth and last Majoor der Chinezen ("Major of the Chinese") of Batavia, Dutch East Indies (now Jakarta). The Chinese Mayoralty was the highest-ranking, Chinese government position in the East Indies with considerable political and judicial jurisdiction over the colony's Chinese subjects. The Batavian Mayoralty was one of the oldest public institutions in the Dutch colonial empire, perhaps second only in antiquity to the viceregal post of Governor-General of the Dutch East Indies.
