Obturator artery is usually a Branch of Anterior division of internal iliac artery. Its frequent variations in its origin and course has drawn attention of Anatomists, pelvic surgeons and Interventional Radiologists. The present study was conducted on Fifty (Formalin fixed) hemi sections of human cadaveric pelvic specimens, which were collected from the cadavers allotted to undergraduate students at department of anatomy, Raja Muthiah medical college, Chidambaram Tamilnadu, during 2015-2017. The pelvis was carefully dissected to study the origin, relations, within the pelvis. The findings were observed and recorded. Origin of obdurator artery was from the Anterior trunk of Internal iliac in 64% of specimen and was variable in 36%of specimen. The variations in obturator artery may lead to surgical complications during pelvic surgeries.
