%X SUMMARY: Due to the great importance of the knowledge about variations occurring in the vascular system to surgeons and professionals who work with imaging, we describe in this article a variation of the origin of the occipital artery. 110 cadavers of male and female individuals had they carotid vascular tree in the region of the neck carefully dissected using loupe magnification and its origin and course were measured as well as a simple diameter. This artery usually branches off from the posterior part of the wall of the external carotid artery at the same level of the facial artery branching however, the two cases presented showed the occipital artery branching off very close to the carotid bifurcation, which characterize it as a trifurcation instead. The occipital artery branching off too close to the carotid bifurcation is a rarity as demonstrated by our results and the its literature is insufficient RESUMEN: Debido a la importancia que tienen las variaciones musculares para cirujanos, como tambi谷n para los profesionales del 芍rea de las im芍genes, describimos dos variaciones de origen de la arteria occipital. Disecamos la regi車n del cuello en 110 cad芍veres de individuos, adultos, brasileros de ambos sexos, determin芍ndose el origen, trayecto y di芍metro de la arteria occipital. La arteria occipital que se origina generalmente de la pared posterior de la arteria car車tida externa, a nivel de la arteria facial, fue encontrada en dos casos, origin芍ndose muy pr車xima a la terminaci車n de la arteria car車tida com迆n, asemej芍ndose mucho a una trifurcaci車n carot赤dea. Este modo de origen de la arteria occipital, pr車ximo a la bifurcaci車n carot赤dea constituye una variaci車n anat車mica muy rara, como tambi谷n lo demuestra la literatura existente
