A donor organism is an individual from which biological material, such as organs, tissues, or cells, is obtained for transplantation or research purposes. The term is commonly used in the context of organ transplantation, where a donor organism provides an organ to a recipient who requires it due to illness, injury, or congenital defects. Donor organisms can be living or deceased individuals, and the source of the biological material can vary widely depending on the specific application.

In organ transplantation, the donor organ must be compatible with the recipient to minimize the risk of rejection. This compatibility is determined by tissue typing, which involves matching the major histocompatibility complex (MHC) antigens between the donor and recipient. The process of organ donation can be voluntary or involuntary, and it is regulated by legal and ethical guidelines to ensure the safety and well-being of both the donor and the recipient.

Donor organisms also play a crucial role in medical research, where tissues and cells are used to study diseases, develop treatments, and test new therapies. In this context, the biological material is often obtained from deceased individuals or from living donors who are willing to contribute to scientific advancements.

The concept of a donor organism extends beyond human medicine to include other species, where biological material is used for research, conservation, and veterinary purposes. In these cases, the ethical considerations and regulatory frameworks may differ, but the fundamental principle of obtaining and utilizing biological material from a donor remains consistent.
