DONAR Asociación de Trasplantes A.C. is a nonprofit association focused on encouraging organ and tissue donation and supporting people who need transplants. Its mission is to build a culture of donation in society and help patients face the transplant process. The organization envisions a more supportive community in which donation is a natural act of solidarity and transplant recipients receive dignified, comprehensive support. Its work is guided by empathy, respect, inclusion, transparency, confidentiality, and collaboration.

DONAR shares educational information about donation, including frequently asked questions and material addressing common myths. It also invites people to register as donors and offers several ways to contribute. Financial donations support its programs to promote donation and transplantation, while in-kind gifts may include medicines, clinical tests, and medical consultations. Volunteers can assist in person or remotely with events, communications, fundraising, patient accompaniment, and other activities. The association also welcomes professional support from medical, psychological, and nutrition specialists, students, and content creators.
