Li Siguang (Chinese: 李四光; pinyin: Lǐ Sìguāng; Wade–Giles: Li Ssu-kuang; 1889–1971), also known as J. S. Lee, was a Chinese geologist and politician. He was the founder of China's geomechanics. He was an ethnic Mongol. He made outstanding contributions, which changed the situation of "oil deficiency" in the country, enabling the large-scale development of oil fields to raise the country to the ranks of the world's major oil producers.

The first original Chinese violin composition "Difficult Road" (Xinglu Nan) is composed in 1919-1920 by Li Siguang, who was pursuing his studies at the University of Birmingham in Britain at that time.
