Khouw Tjeng Tjoan, Luitenant-titulair der Chinezen (Chinese: 許淸泉; pinyin: Xǔ Qīngquán; Pe̍h-ōe-jī: Khó͘ Chheng-chôaⁿ; born 1808 — died in 1880) was a Chinese-Indonesian magnate and landlord.
He was raised in 1856, together with his brother Khouw Tjeng Kee, to the honorary rank of Luitenant-titulair der Chinezen, but without any of the entailed responsibilities in the civil administration.
[4] His funeral in 1880 attracted - according to contemporary newspapers - thousands of onlookers who thronged the whole stretch of Molenvliet, all the way to Kebon Jeruk.
[7][5] Nonetheless, at least one writer commented that the late magnate was, in fact, unpopular among the general populace due to his "conceit, wrathfulness and twisted character".
[8] Six of the Luitenant's sons later served as Chinese officers in the colonial bureaucracy, most notably Khouw Kim An, the fifth and last Majoor der Chinezen of Batavia.
