Research on Toona sinensis is important for its cultivation in China and provision of a high�??quality timber resource. We used the GB1927-91 Test Method to examine the anatomy and physico�??mechanical properties of Toona sinensis wood. We found that fiber morphology is shaped, on average, after 13 years of growth, with an aspect ratio of 46.18, double wall thickness of 11.00μm, fiber wall cavity ratio of 0.56, and cavity diameter ratio of 0.76. Average length and width of vessel elements was 383.52μm and 143.98μm, respectively, basic density was 0.415g/cm3 and air dry density was 0.475g/cm3. The wood may be described as a �??light and low type�?� timber with differences in shrinkage of 1.93, wood bending strength, modulus of elasticity and compressive strength of grain rolls of 67.85MPa, 6179.82MPa and 38.23MPa, respectively, an integrated strength of 106.08MPa, and a comprehensive quality factor of 2556.1�?105Pa. Based on our findings, Toona sinensis may be considered to produce a form of high-quality wood
