Cheong Fatt Tze (born Chang Chin Hsun; c. 1840–1916), also known as Tjong Tjen Hsoen, Thio Tiauw Siat or Zhang Bishi was a Chinese industrialist, politician and philanthropist.

Spending the majority of his life residing in Malaya and the Dutch East Indies, he was a powerful Nanyang business magnate and a first-class Mandarin of China; he was made Consul-General in Singapore and economic advisor.

As a result, Cheong Fatt Tze migrated to South-East Asia together with other coastal Chinese families to seek their fortune.

His business was based on agricultural products such as rubber, coffee and tea but he branched out to the financial sector by acquiring a bank.

In the course of his work, he occasionally resided in Penang and owned a mansion in Leith Street, which stands to this day as protected heritage building.

The Chinese government sent a high-ranking official to his funeral and ordered the National Archives to record his life in historical documents so that his contributions would always be remembered.

Both the British Raj and the Dutch authorities ordered flags to be flown at half mast to honour the man who was known as "the Rockefeller of the East".

He had eight wives and owned many residences throughout his trading empire (mostly Southeast Asia) but made Penang his base, where he raised his six sons.
