Blood samples were obtained from10 male and 10 female goats from different veterinary ranges of Batticaloa district, Eastern Province, Sri Lanka to explore influence of sex on the haematological profile of goat. Hematological parameters such as total White Blood Cell count (WBC count), neutrophils, lymphocytes, monocytes, eosinophils  basophils counts, Red Blood Cell count (RBC), Haemoglobin (Hb), Mean Corpuscular Volume (MCV), Mean Cell Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) were analyzed. The values of lymphocytes, eosinophils, monocytes, basophils, MCV and MCHC were higher (P<0.05) in male goats than female goats. The values of WBC, neutrophils, RBC, Hb and MCH were higher (P<0.05) in male goats than female goats. Values of WBC, neutrophils, eosinophil, monocyte, RBC, MCV and MCH were significantly influenced by sex.
