    The aim of this study was to determine some of the physical and mechanical properties of Turkish hazelnut (CoryluscolurnaL.) wood.Hazelnut is an endemic species in Turkey and the trees used for the study were taken from the Pınarbaşı District of KastamonuProvince. As a resultof experiments carried out to evaluate the physical properties, it was found that the values of dry and air dry density were 0.636 gr/cm3 and 0.672 gr/cm3 , radial, tangential and longitudinal swelling values were 4.60%, 7.48% and 0.41%, radial, tangential and longitudinal shrinkage values were 5.11%, 8.49% and 0.59%, respectively. According to the related standards, the mechanical properties ofbending strength (98.5 N/mm2), modulus of elasticity in bending (8273.4 N/mm2), compressive strength parallel to the grain (50.09 N/mm2 ), dynamic bending strength (impact strength)(0.71 kN/cm), tensile strength perpendicular to the grain (5.09 N/mm2 ), and hardness values of cross, radial and transverse sections (72.55 N/mm2 , 47.32 N/mm2 , 46.13 N/mm2, respectively) were also determined.
