Dalbergia cochinchinensis, the Thailand rosewood, Siamese rosewood, or tracwood, (Thai: พะยูง: Phayung ; Vietnamese: Trắc (or Cẩm lai nam bộ); Khmer: ក្រញូង: Kranhung ; Lao: ກະຍູງ: Kayung ; Chinese: 酸枝木: Suān zhī mù ) is a species of legume in the family Fabaceae.

It is a tree yielding valuable hardwood found in Cambodia, Laos, Thailand, and Vietnam.[3] In 2022 its status was re-evaluated as Critically Endangered caused by illegal logging and smuggling.[4] Conservationists project that the species could be extinct within 10 years (by 2026).[5]

Due to its pioneering characteristics, drought tolerance, and nitrogen-fixing ability, it shows potential for restoring degraded forests and deforested sites. Therefore, sustainable plantation of the tree can serve both goals of conservation and forest landscape restoration.[6]

University of Oxford published the transcriptomes of Dalbergia cochinchinensis and five other Dalbergia spp.[7] It was found that D. cochinchinensis had fewer R genes than the co-occurring Dalbergia oliveri.
