Sukhumala Marasri (Thai: สุขุมาลมารศรี, RTGS: Sukhumanmarasi, Sukhumālmāraśrī; 10 May 1861 – 9 July 1927) was a daughter of King Mongkut (Rama IV) and his concubine, Samli (เจ้าคุณจอมมารดาสำลี).

She had 5 full siblings, including the famous Princess Napaborn, and from her father's side, she was a half-sister to King Chulalongkorn (later her husband), Queens Sunanda Kumariratana, Savang Vadhana, and Saovabha Phongsri.

When she was ten years old, King Mongkut died and was succeeded by Sukhumala Marasri's half-brother, Prince Chulalongkorn.

Her son, Prince Paribatra Sukhumbandhu was a prominent figure in Siamese politics during the later part of the absolute monarchy, often credited as the man behind King Prajadhipok's throne.

The prince served as Minister of the Interior at the time of the Siamese revolution of 1932, and he was captured by the Khana Ratsadon (the People's Party) and placed under arrest.
