Introduction: Fine needle aspiration (FNA) cytology is a widely utilized tool for the diagnosis of thyroid lesions with a high degree of sensitivity, specificity and diagnostic accuracy. Materials and methods: A retrospective hospital based study was done in which a total of 90 cases of thyroid lesions were included. All cases were categorized according to the Bethesda system for reporting thyroid cytology(TBSRTC) into unsatisfactory , benign, atypia of undetermined significance or follicular lesion of undetermined significance, follicular neoplasm or suspicious for a follicular neoplasm, suspicious for malignancy,  malignant. Results: The study included 90 cases. Female to male ratio was 2.6:1, and maximum number of cases was observed in age group 21–30 years. Out of 90 cases, 4 cases were diagnosed as unsatisfactory ,55 as benign ,4 as atypia of undetermined significance or follicular lesion of undetermined significance,09 as follicular neoplasm or suspicious for a follicular neoplasm, 07 as suspicious for malignancy,  and 11 as malignant. Most common benign lesion was nodular goitre representing the majority of benign cases (72.7%), while papillary carcinoma was the most frequent malignant lesion (72.7%). Conclusion: We conclude that FNAC is a simple, safe, minimally invasive and reliable technique for evaluation of thyroid lesions.
