Phraya Ratsadanupradit Mahitsaraphakdi

Phraya Ratsadanupradit Mahitsaraphakdi (พระยารัษฎานุประดิษฐ์มหิศรภักดี; 1857–1913, born Khaw Sim Bee (คอซิมบี๊;, ) was a Thai Chinese provincial administrator. He was the youngest of the six sons of Khaw Soo Cheang, a trader from Zhangzhou in China.

As a member of the Khaw family of Ranong which held the governor's post in Ranong for generations, Khaw was assigned to become governor of Trang in 1890. His most significant contribution was the introduction of the rubber tree to Thailand, which at his time was only grown in British Malaya. It has since become one of the major crops of Thailand. In addition, he also initiated the connection of Trang with Nakhon Si Thammarat and Phatthalung by road as well as the railroad connection to Nakhon Si Thammarat, one of the first railways in Thailand, kickstarting the development of Southern parts of Siam.

In 1902, he was assigned to become the commissioner of Monthon Phuket and held the post until his death in 1913.

A monument commemorating him was erected in the city of Trang. In 1992, he was also honoured as one of the five most distinguished government officials in administration.

The Khaw clan was given the noble title ‘Na Ranong’ by the King of Siam in 1913 (Rama VI).
