Objective: This study aimed to reveal the coronary veins and the branches that join it to provide venous drainage of the heart in Southern Karaman sheep. Material-Method: Eight Southern Karaman sheep’s heart tissues were used in the study. Latex injection techniques were used to determine the coronary veins and the branches that join it for providing venous drainage of the heart.Result: In the study, vena cordis magna, vena cordis media, and vv. cordis dextra was observed as venous drainage providing vessels. The vena cordis magna began in the lower third of the sulcus interventricularis paraconalis, called vena interventricularis paraconalis. This vein reached the sulcus coronarius and continued as vena circumflexus sinister. Vena cordis media was named as vena interventricularis subsinosus in sulcus interventricularis subsinosus. The vv. cordis dextra was responsible for the venous drainage of the facies atrialis of the heart.Conclusion: In the evaluation of the study findings, it was determined that the coronary veins and the branches joined it of Southern Karaman sheep were mainly similar to other sheep breeds in the literature. Still, there were some anatomical differences, for example; vena distalis ventriculi sinistri was opening into vena circumflexus sinister, vena apicis cordis was absent, vena semicircumflexa dextri was present.
