Dr Chen Su Lan (Chinese: 陳樹南; pinyin: Chén Shùnán; 13 February 1885 – 5 May 1972) was a Singaporean doctor, and one of the first locals to graduate from medical school.

He founded the Chinese Young Men's Christian Association (YMCA) in 1945 and formed the Chen Su Lan Trust in 1947.

He recognised that opium addiction was a grim social problem, not helped by the fact that the colonial government monopolised the sale of the drug as means to regulate its use.

When the Pacific War broke out in December 1941, the Japanese army made steady progress in its conquest of the Malayan peninsula.

Upon landing on shore at a mangrove forest, Chen returned home only to be detained by the Kempeitai (Japanese military police).

The Trust disbursed funds and land to Christian organisations like Scripture Union, and for the founding in 1968 of the Methodist Children's Home which was named after him.

In 1969, Chen published a book entitled Pompong and Oxley Rise, which recounted his childhood days and his experiences during the Japanese Occupation.
